ROBUST ADAPTIVE CONTROL DESIGN FOR MULTI-INPUT UNCERTAIN CHAOTIC SYSTEMS TOLERANT TO UNKNOWN ACTUATOR FAILURE

摘要

In this paper, the problem of online estimation of unknown system uncertainties and disturbances of multiinput unknown chaotic systems and the design of a robust adaptive controller, according to the estimation information, tolerant to unknown faults that may be occurred in the system actuators is considered a model reference adaptive control scheme is proposed for chaotic multi-input systems. Only the dimensions of the chaotic systems are required to be known. Based on Lyapunov's stability theory, new adaptive control laws are synthesized to accommodate system uncertainties, disturbances, actuator failures, and system nonlinearities. The performance of the proposed controller design is illustrated through a numerical example.
