摘　　要：本文提出一种智能 PI 控制器,并用作交流调速系统的转速调节器。智能 PI 控制器能根据系统运行状态动态地改变调节器结构和参数,有效地缓解了传统 PI 调节系统快速性和平稳性的矛盾,改善了调速系统的动态性能。仿真与实验结果表明:在相同的负载转矩扰动下,智能 PI控制系统的动态速降和恢复时间均小于积分分离的 PI 控制系统。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.
