摘要

This paper investigates an adaptive fuzzy decentralized control approach for a class of nonlinear systems with unknown control direction and different performance constraints. In the control design, the different performance constraints, that are the prescribed performance error constraints for some subsystems and the asymmetric time-varying output constraints for the others, can be unified as one form by selecting proper performance functions. The fuzzy systems are employed to approximate the unknown nonlinear functions, and an adaptive fuzzy decentralized controller loaded with the Nussbaum-type function is developed to resolve the unknown control direction issues. It is proved that all the signals in the resulting closed-loop systems are bounded and that the different performance constraints for the subsystems can be achieved simultaneously. The performance of the proposed scheme is highlighted through the simulation example. (C) 2018 Elsevier B.V. All rights reserved.
