The Design Of Fuzzy Controllers Based On Genetic Algorithm

In recent years ,Fuzzy control has been extensively researched．Although fuzzy logic controllers have been successfully applied in many complex industrial processes,the questions of quantification factors,control rules and membership functions rely to a great extent on empirical and heuristic knowledge．So the acquisition of these parameters is a bottleneck problem． In this paper,a kind of CGA is used to optimize fuzzy logic controllers,and the idea in the method of control rules optimization is introduced with emphasis．The optimal or sub-optimal control rules are obtained by using CGA．In the same time,in order to demonstrate the performance of the designed controller,we simulated it in MATLAB and applied it in boiler's water temperature control．The result of the simulation and control illustrates that it has good dynamic performance and robust．...
