| Abstract | ||
| Sliding mode control algorithm that uses fuzzy saturation function is designed in this paper for nonlinear system. The fuzzy saturation function is suggested to improve the accuracy and the robustness of the sliding mode control which are partially lost when using a fixed boundary layer. The fuzzy saturation function is simple, in the sense that both the membership functions and the rule base are simple. The overall control algorithm has stability assurance for the closed-loop controlled system; therefore, it may be applied to control different systems, in this paper this algorithm is applied on nonlinear SISO system with 10%parameter uncertainty and nonlinear disturbance. Simulation results show that the developed algorithm has good control performance with negligible chattering. | ||
