Fuzzy-Based Hybrid Control for Nonlinear Multivariable System

摘要：

Hybrid controller based on fuzzy logic system is designfor a class of nonlinear multivariable systems. The nonlinearsystems involve plant uncertainties and external disturbances.The controller is based on a combination of the H ∞ trackingtheory, fuzzy logic system and supervisor control algorithm(SCA). The robust stability of the control system is proofed the paper. When apply the hybrid controller, all the states andsignals of the closed-loop system are bounded and H ∞tracking performance is guaranteed. Consequently, the controlperformance of the system is greatly improved. The hybridcontroller can be applied to more general nonlinear systeminvolving a large class of uncertainties and variations. At last thesimulation result is given.
