The application in adaptive control for differential evolution algorithm

Aiming at the complex nonlinear system, a PID self-adaptive control method based on the DE algorithm is stated in the paper. Based on on-line optimization of PID controller parameters by the DE algorithm, the desirable control effect is obtained. An application of this method to the control of the continuous Stirred Tank Reactor (CSTR) system which is a complex nonlinear system is studied. Simulation results show the validity of the method.
