Abstract
Particle Swarm Optimization(PSO) has been a novel global optimization algorithm which is based on swarm intelligence.It is easy to be realized and already applied to many fields.In order to reform the problem of PID controller parameters,this paper presents a novel improved PSO algorithm,the three parameters of PID controller are optimized by this algorithm.The structure of controller is simple and the simulation result proves that this controller is feasible and effectual.
