摘要
基于矩阵变换器(MC)直接转矩控制系统(MC-DTC)应用无速度传感器技术以及将三者融合的技术讨论了速度自适应辨识方法与满足系统融合要求的控制策略。仿真和实验结果表明系统动态响应好,同时能发挥MC和DTC的优势,是一种高性能的交流调速系统。
The speed sensorless mostly applied to vector control system of electric machine, whereas seldom applied to direct torque control （DTC） system. In this paper the speed sensorless technology based-on matrix converter （MC） direct torque control system （MC-DTC） and their fusion technology were studied. The speed adaptation distinguish means and the control strategy which satisfied with system of fusion was discussed. Simulation results showed that dynamic response was also fast. It＇s a high-powered AC speed governing system, the predominance of MC and DTC were exerted at the same time.
