dtc for 3phases induction motor

This paper describes a torque ripple reduction technique with constant switching frequency for direct torque control (DTC) of an induction motor (IM). This method enables a minimum torque ripple control. In order to obtain a constant switching freq

随着异步电机开始在交流调速领域占统治地位，针对高性能异步电机的调速系统 研究得到广泛关注。特别是 20 世纪 80 年代直接转矩控制（DTC）的出现，以其简洁高 效的控制方式，进一步提高异步电机的性能。但传统 DTC 存在转矩和磁链滞环宽度使 得稳态时也会产生转矩脉动。因此高性能控制需要窄的滞环宽度,相应要求高逆变器开 关频率。大功率场合下必须低开关损耗和良好转矩控制性能，传统 DTC 难以同时满足 需求。 -With the beginning of the AC in

In this paper, direct torque control (DTC) of fivephase induction motor is developed. A novel DTC scheme is proposed, where fast torque response with low ripple in the stator flux and torque of five-phase induction motor can be achieved. In c
