Abstract

Presents a switching type neuro‐fuzzy control synthesis. The control algorithm supposes as a component part a neurocontrol designed to optimize a performance index. Whenever the neurocontrol saturates or a certain performance parameter of the system decreases, the scheme of control switches to a feasible and reliable fuzzy logic control. Describes the procedure of return to the optimizing neurocontrol which is essential. This methodology of control synthesis ensures antisaturating, antichattering and robustness properties of the controlling system, as illustrated by numerical simulation in the case of a primary flight controls electrohydraulic servo actuator

Abstract

This paper is about how a command system allocated resources under profound uncertainty. The command system was the Soviet economy, the period was Stalin's dictatorship, and the resources were designated for military research & development. The context was formed by the limits of the existing aviation propulsion technology, the need to replace it with another, and uncertainty as to how to do so. We observe the formation of a quasi-market in which rival agents proposed projects and competed for funding to carry them out. We find rivalry and rent seeking, imperfectly regulated by principals. As rent seeking spread and uncertainty was reduced, the quasi-market was closed down and replaced by strict hierarchical allocation and monitoring. In theory, a dictator cannot commit to refrain from taxing the returns from today's effort tomorrow; therefore, we expect agents in a command system to seek only short-term returns from quasi-market activity. Agents’ willingness to invest in the Soviet quasi-market for inventions is ascribed to a reputation mechanism that enforced long-run returns.
