基于改进合作协同进化算法PID整定
PID Parameters Optimization with Improved Cooperative Coevolution Algorithm
摘要
Abstract
Aiming at the parameter tuning problem of PID control in complex system,a parameter optimization method of PID controller based on improved collaborative coevolution has been proposed to realize the optimal combination of three parameters of PID in the co-evolutionary way under the given performance index.Based on the PID controller model,a more optimized objective function of PID parameters has been designed.Combined with the cooperative co-evolutionary algorithm for optimization of the parameters,the group sorting strategy before PID parameters co-evolution is put forward based on the cooperative evolution algorithm.The optimal group is selected as the next generation of representative combination of co-evolution in accordance with results of group sorting strategy to evaluate the merits of packet sorting.The simulation results show that the proposed algorithm has better optimization effect than the traditional one,and has fast convergence speed,strong adaptability and high precision,with a better application prospects.关键词
