Optimization design method of fuzzy controller based on GA

It is presented in this paper a comprehensive optimization design and simulation analysis method of the fuzzy controller. The method based on GA. Firstly, it uses fuzzy control system toolbox to construct a fuzzy controller, then it optimizes the control rules and parameters of the fuzzy controller by GA, finally, with the simulation linker, it builds an emulation model of a second-order system with delay and analyzes the dynamic characteristics of the whole system according to the step response. The simulation results show that the system can meet the target and design the fuzzy controller with high efficiency.
