Fractional-order PID Controller Tuning Based on Genetic Algorithm
Because the fractionalorder systems model is complex and the fractionalorder controller requires more tuning parameters than that of integerorder controller, the tuning parameters method of fractionalorder PID controller is difficult to obtain. In order to improve the accuracy of fractionalorder PID controller, the character and the designing method of fractionalorder PID controller is analyzed in this paper, and the genetic algorithm is introduced to the design of fractionalorder PID controller. By using the genetic algorithm to optimize the corresponding parameters, a better PID controller which has a superior is obtained, the error of fractionalorder controller is avoided and the tuning efficiency is improved. The results of simulation show that the controlling effect of the fractionalorder PID PID controller is better than that of the integerorder PID controller.
