Fuzzy adaptive control design for a class of nonlinear systems with scalers and saturators
|
Abstract:
A class of nonlinear systems with uncertain homogeneous functions is discussed. At first, the inputs and outputs of the T-S fuzzy logic system are constructed to form the extended fuzzy logic system(EFLS) based on the definitions of scalers and saturators; and then a design method of fuzzy adaptive control with adjustable scaler parameters is proposed by using the extended fuzzy logic systems. Because the method does not depend on the number of the rule base, the design method not only reduces the number of on-line parameters but also guarantees the uniformly ultimately bound(UUB) of the system. Finally, the simulation shows the validity of the proposed method.
