Abstract The boundary layer approach is the most popular method to reduce the chattering phenomenon in sliding mode control (SMC) for uncertain nonlinear systems. This paper applies the fuzzy sliding mode structure based on the boundary layer theory which is used as speed controller of an indirect field-oriented control (IFOC) of an induction motor (IM) drive. A fuzzy inference system is assign...

A novel sliding mode controller based on Takagi-Sugeno fuzzy model is designed for a class of nonlinear systems to tackle the nonlinear control problems with modelling uncertainties, time varying parameter fluctuations and external disturbances. A numerical example is simulated to verify the performances of the proposed control strategy, and the simulation results show that the controller desig...

This paper presents a fuzzy controller to solve a master-slave chaos synchronization problem. At first, the method of traditional sliding mode control is considered, which utilizes the discontinuous sign function to make the system state reaching a sliding surface. Next, fuzzy rules are determined according to the Lyapunov theorem, and the fuzzy controller is designed for chaos synchronization....
