摘要
研究一种基于矩阵式变换器的异步电机控制策略,分析了异步电机的直接转矩控制方法和矩阵式变换器的空间矢量调制,给出了在直接转矩控制方案中,矩阵式变换器矢量电压的选择.这一控制策略同时实现了矩阵式变换器的空间矢量调制和异步电机的直接转矩控制.利用MATLAB仿真平台实现了该控制策略,仿真结果表明:采用这一控制策略的调速系统具有良好的静、动态性能,并且保持了单位功率因素.
The direct-torque control strategy for asynchronous electromotor based on matrix converters is studied. The principle of direct-torque control, the space vector modulation of matrix converter （MC） and the selection of MC space vector voltage based on direct-torque control are systematically analyzed. Realization of this strategy based on MATLAB and the simulation results are given in this paper, which verify that this control strategy results in good static and dynamic performance of speed control system, and maintains the unity power factor.
