The Tuning of Fractional Order PI[lambda]D[mu] Controller Parameters Based on Immune Clone Selection Algorithm

Abstract

The application technology of traditional PID controller has been very mature, but in complex industrial production, the controlled object often is non-linear or time-varying, traditional PID controller often can not reach the desired effect, which introduces the concept of fractional order PI?D? controller. Fractional order PI?D? controller is a generalization of traditional PID controller and it has the very good effect to the system that has nonlinear and time-varying links, but the scarcity of tuning methods of the fractional order PI?D? controller is still a problem to be resolved. This article presents a new method that tunes the parameters of fractional order PI?D? controller by using immune clone selection algorithm and then implements simulation by using matlab. The simulation results demonstrate that use fractional order controller can get better control effect than traditional PID controller.
