一种改进遗传算法的PID参数整定研究
Research on PID Parameter Tuning Based on an Improved Genetic Algorithm
摘要
Abstract
PID control is the most common control method so far. It has the advantages of simple structure,good stability,reliable opera-tion,easy adjustment and so on,which is widely used in the field of industrial control. In PID control,the stability and speed of the control system is determined by the choice of PID parameters. In the traditional PID parameter tuning,the trial and error method is used widely. However,this method is time-consuming,and it is difficult to meet the requirements. In order to solve this problem,a PID parameter tun-ing method is proposed based on improved genetic algorithm. The selection operator,crossover operator and mutation operator are im-proved. The method makes up for shortcomings which the basic genetic algorithm is easy to fall into local optimum. It speeds up the con-vergence rate of genetic algorithm. Simulation show that it is feasible.关键词
