The improved particle swarm optimization(PSO) is a novel evolutionary algorithm occurring recently,which has good optimization effects on continuous functions.Through using PSO to optimize the PID parameters of main-steam temperature control,the disadvantages of traditional control are analyzed,and the robust performance of the whole system is improved.By applying this control system,main-steam temperature is well controlled and the economical benefit is improved,which illuminate that the improved particle swarm optimization algorithm is simple for optimizing,and the control system obtains steady dynamic performance and strong robustness,and easy to parallel.The simulation results show the high efficiency of the proposed optimal method,being an ideal method of PID parameter optimization.
