一种减少 SRM 转矩脉动的控制策略研究

摘要

Due to its simple structure and superior performance ,switched reluctance motoris widely used in many envi‐ronments ,but its own structure has led to the generation of torque ripple .In order to solve this problem ,a strategy to re‐duce the torque ripple of SRM ,Direct Torque Control is researched .The Matlab simulation of switched reluctance motor based on this strategy is carried out .The simulation results show that the direct torque control can effectively reduce the torque ripple of switched reluctance motor ,the control method is simple and the system has good performance .%开关磁阻电机（SRM ）由于其简单的结构和优异的性能，应用范围很广泛，但其本身结构导致了转矩脉动的产生，为了解决这个问题，文章研究了一种控制策略—直接转矩控制，以减少开关磁阻电机的转矩脉动。文章详细阐述了直接转矩控制的基本原理和实现方法，并对基于这种控制策略的开关磁阻电机的控制进行了 Matlab 仿真。仿真结果表明直接转矩控制能够有效地减少开关磁阻电机的转矩脉动，且控制方法简单，系统具有良好的动静态性能。
