Description: Water plus acid control system for thermal power plant control system exists object is difficult to establish, nonlinear and time-varying characteristics, using the improved particle swarm optimization algorithm to optimize PID parameters, so that the controller can be different in different ambient temperatures. PID parameters. Actual operating results show that the system is able to overcome the interference caused by the ambient temperature, the circulating water pH value is controlled within a given range of values.
