Abstract: This paper develops a new design method of fuzzy sliding parallel distributed compensation (PDC) controller applied to deal with some non-linear systems subject to unpredictable but bounded disturbances. A new fuzzy integral sliding surface vector based on the PDC concept is defined for the proposed fuzzy sliding PDC control. The Lyapunov stability condition is guaranteed in this design to develop strictly robust sliding PDC gains Fi. This fuzzy sliding PDC controller is applied to control the ecological system and pendulum system. The simulation results of this controller demonstrate that the performance and robustness are better than that with state feedback control and fuzzy PDC control.
