摘　　要：为进一步提高异步电动机的调速特性,分析了有速度传感器矢量控制存在的问题,设计并搭建了交-直-交两电平双PWM四象限电动机实验平台,在该平台上实现了绕线式异步电动机转子变频无速度传感器矢量控制系统。仿真和实验结果,均验证了理论分析的可行性。In order to further improve the speed regulation characteristics of asynchronous motor, the problems of speed sensor vector control have been analyzed. An experimental platform of AC-DC-AC two-level double PWM four-quadrant motor has been designed and built. A speedless sensor vector control system of winding asynchronous motor with rotor frequency conversion has been realized on this platform. The simulation and experimental results verified the feasibility of the theoretical analysis.
