PID Parameters Optimization and Its Engineering Application

The performance of PID controller depends on the combination of the control parameters. This paper puts emphasis on the study of particle swarm optimization (PSO) in parameter optimization for PID controller. Firstly, according to a great amount of experiment, a set of formulas were proposed in dealing with PID controller optimization for self-balanced and non-self-balanced objects respectively. Then corresponding optimization procedures had been programmed with PSO, and tests show the procedures are effective.
