| Abstract: | This paper presents an intelligent PI controller, which is applied in the speed controller of AC drive system.According to operation state, intelligent PI controller can adjust its structure and parameters online, which can remarkably improve dynamic performance of the system. Comparing with conventional PI control system, it successfully solves the contradiction between quickness and smoothness. Simulation and experiment results haven shown that: under the same load disturbance, both dynamic speed change and recovery time of proposed intelligent PI control system are less than that of integral separated PI control system. |
