Controlling structures and properties of controller effect dynamic properties of all the system in AC servo system. Base on PMSM, regulating the current loop of AC servo system is the basic of high performance servo systems. Three loops controlling structure of AC servo system was analyzed by this paper. In this paper, dynamic mathematical model of closed current loop were established and simplified...
This paper proposes a new PID parameter tuning method using Chaotic Particle Swarm Optimization (CPSO) with ICMIC. The method is implemented into the PID tuning of the position control system, where the transfer function represents a plant model of a servo system. The PID parameter is computed by CPSO-based, PSO-based and ZN-based PID tuning method according to the obtained model, respectively. The...
Addressing to the difficulties in PID parameter tuning, low accuracy in temperature controlling and the dissatisfaction in high exactitude extrusion processing of the present PID controllers, a new kind of PID controller based on RBF neural network is proposed. It can not only obtain a higher accuracy in temperature controlling, but also infinitely approach the nonlinear system with quicker and more...
