Research of Direct Torque Control Technology Using in Three-phase Asynchronous Motor Control System

为满足传动系统对性能越来越高的要求,对直接转矩控制技术的理论做了深入的研究,对直接转矩控制中的电压矢量选择规律进行了详细分析,以Matlab/Simulink为工具设计了整个电机控制系统的仿真模块,对异步电机直接转矩控制下的运行性能进行了仿真研究,结果表明系统有很高的静、动态性能。

To meet the request of the more and more high performance of the transmission system, this paper makes a deep research of the direct torque control technology theory, gives the detailed analysis of the voltage vector selection rules in the direct torque control, design the simulation module of the motor control system based on the Matlab/Simulink tool, makes the simulation research of the asynchronous motor performance controlled by the direct torque control technology, the results show that the system has high static and dynamic performance.
