The research of Multi-mode PID controller parameters optimization based on cross-entropy method

This paper introduces cross-entropy optimization method and Multi-mode Proportional-Integral-Derivative (Multi-mode PID) control algorithm. With features of simple control parameter setting, low computation complexity and high robustness, the cross-entropy optimization method is applied to iterative optimization in Multi-mode PID controller parameters design. In present paper, simulation investigations for an industrial process are carried out, and the feasibility, effectiveness and good performance of the proposed method is verified.
