This study proposes a predictive neural network model reference decoupling control method for the coupling problem between the leg joints of hydraulic quadruped robots, and verifies its decoupling effect..

The machine–hydraulic cross-linking coupling is studied as the coupling behavior of the hydraulically driven quadruped robot, and the mechanical dynamics coupling force of the robot system is controlled as the disturbance force of the hydraulic system through the Jacobian matrix transformation. According to the principle of multivariable decoupling, a prediction-based neural network model reference decoupling control method is proposed; each module of the control algorithm is designed one by one, and the stability of the system is analyzed by the Lyapunov stability theorem.

The simulation and experimental research on the robot joint decoupling control method is carried out, and the prediction-based neural network model reference decoupling control method is compared with the decoupling control method without any decoupling control method. The results show that taking the coupling effect experiment between the hip joint and knee joint as an example, after using the predictive neural network model reference decoupling control method, the phase lag of the hip joint response line was reduced from 20.3° to 14.8°, the amplitude attenuation was reduced from 1.82% to 0.21%, the maximum error of the knee joint coupling line was reduced from 0.67 mm to 0.16 mm and the coupling effect between the hip joint and knee joint was reduced from 1.9% to 0.48%, achieving good decoupling.

The prediction-based neural network model reference decoupling control method proposed in this paper can use the neural network model to predict the next output of the system according to the input and output. Finally, the weights of the neural network are corrected online according to the predicted output and the given reference output, so that the optimization index of the neural network decoupling controller is extremely small, and the purpose of decoupling control is achieved.

Shows how methodological choices are not theoretically neutral. Draws attention to ways in which different analyses of the same data may affect inferences about teachers’ policy coupling in school systems. In this case study of the Jerusalem school system the authors used three statistical procedures to assess teachers’ perceived policy alignment among three organizational levels (teachers; schools; and the Israel Ministry of Education (IMOE)). Analyses using descriptive statistics show that the perceived policies at the three levels are similar, thus giving some support to the theory of tight coupling. Smallest Space Analysis shows that there are close connections between the teachers’ own policies and those they impute to schools, but not those they impute to the IMOE. These findings support a moderate view of organizational coupling. Finally, variance component analyses find almost no consensus in schools regarding policies. In contrast to the other approaches, these models support a loose coupling hypothesis. In overview, shows how methodological choices affect the support given to rival theoretical hypotheses. Suggests that theoretical looseness with regard to explicit falsification conditions is at the root of contrasting evidence about teacher coupling in school systems.

The purpose of this paper is to review and synthesize the attributes of loose and tight coupling in educational organizations. In addition, it is aimed to determine whether this phenomenon has value and strategies to offer for the current educational administration and research.

Integrative literature review and content analysis, assisted by Atlas.ti software, were used as the methods of this paper. Review data included 32 articles from peer reviewed journals.

Conceptual framework of continuum of organizational couplings in educational organizations was generated. Elements of the framework include the features of coupling concepts within the continuum, components of couplings, contributory types of organizational couplings and the elements of leadership and change process with emerging strategies, as well as the element of cultural context. In this paper, elements of continuum of couplings and leadership will be emphasized.

Findings have practical implications for the management and leadership in educational organizations, and for the researchers in the field for future research purposes.

Findings have social implications for both teaching staff and administration in educational organizations, by highlighting the attributes of loose and tight coupling, and their connections with leadership, change process and cultural context.

The paper presents a distinctive synopsis of the educational administration literature, in the context of loose and tight coupling, with the time span of four decades.

This paper investigates how an externally imposed programme with the objective of improving the income of the poor is measured and managed by a public agency in Malaysia.

A qualitative case study approach is used in this research. The data were collected over a three-year period with interviews conducted with key officers at various levels ranging from the Ministry to the agency responsible for implementing the programme.

The introduction of the programme into the organisation's activity was loosely coupled, reflected by the way in which the programme was being implemented. There was some inter-dependency between the three hierarchical levels in terms of their performance measures and targets, responsibilities and reporting. There were no significant changes to the organisation's practices and weak linkages between the programme's objective, the formulation of indicators and the way the information was used in performance assessment. The lack of integration of the programme resulted in high importance being attached to measurement and reporting, rather than focusing on the achievement of the programme objective.

This paper contributes to understanding the performance management issue regarding the vertical and horizontal coupling of a system in relation to an externally derived programme.

This paper investigates the extent to which externally led benchmarking may have facilitated performance management design and use in Malaysian local authorities.

A longitudinal qualitative study of local authorities in Malaysia was undertaken, comprising interviews with key officers during the introduction of process-based key performance indicators (KPIs), and following the imposition of benchmarking (i.e. relative performance evaluation) on local authorities. Complexity theory was used in the analysing and theorising of data.

External benchmarking mechanisms facilitated only operational performance management, with strategic performance management merely ceremonially adopted. As the focus was on mainly operational KPIs, strategic goals were not translated into detailed action plans and outputs at departmental level. In addition, operational and strategic performance management packages were decoupled. Thus, the efforts of external actors resulted in operational controls suppressing rather than facilitating strategic processes.

There is a need to transition from purely externally led benchmarking to internally driven benchmarking in local government, whereby benchmarking forms part of the interactive performance management mechanisms that lead to institutional learning and improvement.

Benchmarking activities should be based on comprehensive analyses of performance management design and use. A reflective approach to continuously identify gaps or weaknesses in performance management systems will enable local government administrators to improve systems and processes in a timely manner to meet stakeholder needs.

This paper explains the impact of central government policy and benchmarking initiatives on other levels of government. We have built on previous literature by examining the connection between external benchmarking and internal performance management design and use in local government. In relation to this, and following calls for research on holistic performance management, the integration between operational and strategic performance management packages was also examined.

Marketing organisations increasingly talk about the importance of integrating their communications, of aligning symbols, messages, procedures and behaviours across formal organisational boundaries. Often this implies tighter central control over communications and other organisational processes. This paper sets out to discuss potential negative consequences of such tight control in terms of organisational incapability to react to market changes in increasingly fluid environments due to a loss of sufficient corporate complexity and diversity.

In response, a flexible integration approach that draws attention to the handling of difference and variety within the context of an integrated communications project is articulated. The paper proposes a framework that balances centralisation and decentralisation through attention to dimensions of endogenous control, tight and loose couplings, networks, and common process rules.

The paper demonstrated that, in order to integrate its communications, an organisation needs to embrace diversity and variety and to balance the wisdom of its many voices with the effort to secure clarity and consistency in its overall expression.

The flexible integration approach advanced in this paper opens new avenues of research, practice and pedagogy, encouraging scholars, practitioners and teachers to explore the following dimensions of integrated communications: reception, variability, organisation, voice, couplings and transferability.

The paper contributes to the literature on integrated communications and corporate communications by addressing the organisational dimensions of integration and suggesting a new avenue of integrated communications research that is far more sensitive to the organisational context in which projects of integration exist and unfold.

Voluntary corporate social responsibility reporting has developed into an everyday activity for many commercial organizations, and scholarly interest in these practices continues to increase. This paper focusses on one subset of these disclosures, namely the figures relating to environmental expenditures and investments published by various organizations. The purpose of this paper is to provide insights into the nature, role and significance of such financial environmental information. Despite their seeming accuracy and preciseness, little is known about how such financial environmental information is constructed and subsequently used in organizational settings.

The paper is based on a qualitative case study focussing on a Finnish energy company. The authors build the investigation primarily on 26 semi-structured interviews with employees at all organizational levels, which the authors supplement with various documentary sources. The interpretation draws on the notion of loose coupling, which the authors use as a method theory to provide a better understanding of this complex organizational practice.

The authors highlight the ambiguous and imprecise nature of the outwardly accurate figures provided by the company. The authors argue that disclosed financial environmental information is only loosely coupled with various dimensions, including the organization’s actual activities, its environmental impacts and organizational decision making.

The findings contrast with those of some prior research, which has considered financial environmental information highly valuable. As for broader implications, the paper discusses the accuracy of public records based on such ambiguous organizational figures.

This study seeks to add to the knowledge of the formation of social positions and power of individuals and their effects on the role of accounting in the development of management control systems (MCSs).

Drawing on institutional and the mobilization of power frameworks, the case analysis explores the development of the role of accounting in the MCS.

The results show that loose coupling between management control routines and formal accounting leaves room for individuals whose roles are important in the development of the MCS. These individuals with central social positions are the glue which enables loose coupling to persist through changes. The organizational culture of a family‐led firm may facilitate the individuals to mobilize power, so that they with central social positions mediate the encoding of institutions into rules and routines as well as the reproduction of the formal rules and informal routines and the relationship between them. Similarly, their own social positions may reproduce.

The paper is of value in showing how the power of an individual over (and in) accounting can be constructed in the MCS. In addition, the discussion is linked to operating in certain transitional economies.

THE Trident has been designed from the outset for the eventual introduction of completely automatic landing.

This research aims to present a novel cooperative control architecture designed specifically for roads with variations in height and curvature. The primary objective is to enhance the longitudinal and lateral tracking accuracy of the vehicle.

In addressing the challenges posed by time-varying road information and vehicle dynamics parameters, a combination of model predictive control (MPC) and active disturbance rejection control (ADRC) is employed in this study. A coupled controller based on the authors’ model was developed by utilizing the capabilities of MPC and ADRC. Emphasis is placed on the ramifications of road undulations and changes in curvature concerning control effectiveness. Recognizing these factors as disturbances, measures are taken to offset their influences within the system. Load transfer due to variations in road parameters has been considered and integrated into the design of the authors’ synergistic architecture.

The framework's efficacy is validated through hardware-in-the-loop simulation. Experimental results show that the integrated controller is more robust than conventional MPC and PID controllers. Consequently, the integrated controller improves the vehicle's driving stability and safety.

The proposed coupled control strategy notably enhances vehicle stability and reduces slip concerns. A tailored model is introduced integrating a control strategy based on MPC and ADRC which takes into account vertical and longitudinal force variations and allowing it to effectively cope with complex scenarios and multifaceted constraints problems.
