| Abstract: | In this paper,according to the characteristics of model uncertainty,nonlinear and time delay of the circulating water adding acid control system in power plant,the improved PSO is adopted in PID parameter optimization.Different parameters can be used by PID controller when environmental temperature changes.The obtained results show that the pH of circulating water can be controlled in a given value range,and the system can restrain the environmental temperature disturbance to get good control effect. |
