Genetic-based Sliding Mode Fuzzy Controller Design

In this paper, we proposed a genetic-based sliding mode fuzzy controller design method to avoid the chattering phenomena in traditional sliding mode controller (SMC), and shorten the hitting time of the controlled system. Chattering reduction is an important issue in the sliding mode controller that has been wildly discussed, and we know that a proper width Φ of the boundary layer of sliding surface can suppress chattering in sliding surface very well. In the other hand, the time that system state hits the sliding surface from initial state is also an important property that influences the performance of SMC. The time can also be shortened via a suitable determination of parameter K. In this paper, a genetic-based method is developed to obtain these two important parameters. An inverse pendulum system is utilized to perform the control effect of the designed sliding mode fuzzy controller
