چکیده
The synthesis algorithms of modern control theory and fuzzy logic have been studied to upgrade the performances of SMC. In this paper, Fuzzy sliding mode control, which takes the features of both SMC and FLC to overcome the disadvantage of chattering and enhancing the robustness of the controller, is presented. The fuzzy sliding mode controller is designed for a class of non linear dynamic systems to tackle the problems with model uncertainties, parameter fluctuations and external disturbances. By this design, the bounds of the uncertainties are not required to be known in advance, and the robust stability of closed loop system is analysed in the Lyapunov sense. A numerical example is simulated with the proposed algorithm, witch consists to control the synchronous motor speed. The simulation results show the effectiveness of the proposed control strategy with desired tracking accuracy and robustness.
