| Abstract: | In this paper,the correlation and inner relation between PID,Fuzzy-PID and FLC(Fuzzy Logic Controller) are analyzed.And then an applicable method for the parameter design of Fuzzy-PID is presented.In addition,the genetic algorithm(GA) is used for the fine-tuning of the initial parameters.The simulation of a second-order linear system under step input is performed and the basic control performances of PID,Fuzzy-PID and FLC are analyzed and compared.The simulation verifies the effectiveness of the proposed method. |
