Abstract:

An adaptive fuzzy tracking control scheme is presented for a class of switched multi-input-multi-output ( MIMO) nonlinear systems with disturbances under arbitrary switching. Adaptive fuzzy systems are employed to approximate the unknown functions on line,and a systematic framework for adaptive fuzzy tracking controller design is given,where the dynamic surface control ( DSC) approach is used to solve the problem of "explosion of complexity"in the backstepping design procedure. According to the common Lyapunov function theory,it is proved that the proposed controller can guarantee the boundedness of all signals in the closed loop system. Finally,the simulation results demonstrate the validity of the control approach.

Key words:  adaptive control systems  fuzzy control  switched systems  backstepping  common Lyapunov function
