本文研究了用电压矢量变频器和感应电动机构成的变频电动机系统。通过对该闭环控制系统数学模型的建立,推导出了它的传递函数。它有着与可控硅直流调速系统极其相似的传递函数,因而可用直流电动机的闭环控制对该系统加以控制。通过实际的测试,得到比较满意的结果。[关键词] 感应电动机;变频器;传递函数;闭环控制Abstract: In this paper, we present a frequency conversion electromotor system organized byvoltage vector transducer and induction-motor. We export the transfer-function of the close-loop control system by establishing its mathematic model. Because of the surprising similitude of the transfer-functions of the close-loop control system and the controllable silicon timing system, we can control the system using the close-loop control of DC electromotor. We also obtain satisfied result by actual testing.Keywords: induction-motor, transducer, transfer-function, close-loop control
