ADAPTIVE FUZZY CONTROL OF A CLASS OF DECENTRALIZED NONLINEAR SYSTEMS AND UNKNOWN DYNAMICS

In this paper, a stable indirect adaptive controller is presented for a class of interconnected nonlinear systems with unknown dynamics and interconnections. The feedback and adaptive mechanisms for each subsystem depend only upon local measurements to provide asymptotic tracking of a reference trajectory. Based on the combination of H8 optimal control and fuzzy logic control using a fuzzy identifier and fuzzy logic control, the proposed decentralized fuzzy control can easily tackle the output tracking control problem in a completely decentralized way. An example is given to illustrate the tracking performance of the proposed method.
