This paper aims to present a cascaded pseudo derivative feedback (PDF) plus pseudo derivative feedback plus pseudo derivative feedforward (PDFF) controller for a permanent magnet synchronous motor (PMSM) to improve the transient response of the system.

Proportional integral (PI) plus PI controller and the proposed PDF plus PDFF controller are designed, stability analysis is performed using the extended root locus method, and the effect of the damping coefficient is also extensively studied to validate the robustness of the proposed controller.

When compared to a cascaded PI plus PI controller, the proposed control approach has a much shorter settling time for the entire system and a 50% reduction in overshoot in stator current under extensive variations in speed with load disturbance.

The proposed controller is programmed into an FPGA Altera Cyclone II and applied to a 1.5 kW laboratory prototype PMSM drive. The effectiveness of the proposed methods has been demonstrated experimentally throughout a wide variable speed range, from 0 to 157 rad/s at different load conditions.

The purpose of this paper is to systematically review and critically examine the international marketing and innovation management research on new service development (NSD) in the context of emerging markets (EM). Research on services in EM, a heterogenous set of countries with an increasing contribution to global economic output, is sparse. This paper attempts to underscore the academic and managerial relevance of the field.

A systematic review of published empirical literature from peer-reviewed journals focusing on an 11-year period, 2010–2020, was undertaken. Further, bibliometric and text mining analyses were conducted using VOSviewer and Leximancer software programmes.

This analysis of 36 journal articles reveals that NSD research is a dynamic field with an increasing number of quantitative, multi-country and multi-method studies encompassing a variety of geographical settings and industries.

Doing justice to this vibrant field of research and its managerial importance, the authors create an overview of existing empirical studies to serve as a repository of knowledge on NSD for both academics and practitioners. Further, the authors offer a thematic and temporal overview of the content of existing studies. Drawing upon the abovementioned, the authors suggest some promising avenues for future research.

In part-I of this review series, research from Afghanistan, Bangladesh, Bhutan, Maldives, Nepal and Sri Lanka was reviewed. The purpose of this paper which is part-II of the series, is to review management research from India and Pakistan over a 25-year period from 1990 to 2014.

A systematic review approach was adopted for this research. As a quality standard for inclusion, articles were restricted to journals rated A*, A, or B by the Australian Business Deans Council in 2013 and either Q1 or Q2 in the Scopus/Imago classification system. The divisions and interest groups of the Academy of Management were used as framework to organize the search results.

A total of 1,039 articles related to India (n = 930) and Pakistan (n = 112) emerged from the search process, with three articles being related to both countries. The research was published in 163 different journals that met the quality criteria. The period under review coincides with the advent of economic liberalization in India and this emerged as a major theme in the India-related research. Other context-specific insights for these two countries are also derived from an ecological and institutional theory perspective.

This research represents the first comprehensive and systematic review of management research in India and Pakistan. As in part-I, the unique review approach allows for strict adherence to a predetermined quality standard while including a wide variety of journals and research traditions.
