基于改进WOA参数优化的反应釜PID控制器
Reactor PID controller based on improved WOA parameter optimization
摘要
Abstract
Since the traditional PID control algorithm in industry is more difficult to achieve good control effect for large time lag and nonlinear system,a PID controller tuning algorithm based on improved whale optimization algorithm(IWOA)is pro-posed.In the algorithm,the nonlinear convergence factor is introduced to consider the exploration and development ability of the equalization algorithm.The positive cosine perturbation factor is introduced to improve the position updating strategy,so as to im-prove the exploration ability of the algorithm and avoid falling into the local optimal situation.The PID controller is subjected to the parameter self-tuning experiments by taking the reactor temperature in the chemical reaction as the object under control.The experimental results are compared with those of the WOA,Z-N tuning algorithm and PSO algorithm,and the superiority of the IWOA in optimizing PID controller engineering is verified.关键词
