摘要
阐述了开关磁阻电机(SRM)直接转矩控制(DTC)策略的原理,指出直接转矩控制的核心在于电压矢量的选择及开关表的建立,给出了DTC在SRM中应用的具体实现方法。对基于直接转矩控制策略的SRM电机转矩控制进行了仿真及试验研究。仿真结果表明,这种策略能够较好的抑制转矩脉动,系统动静态特性良好,实现方法简单。
It is presented a strategy of direct torque control which is applied to switched reluctance motors. The core of this strategy is the option of voltage vector and how to establish the switch list. The specific scheme of this strategy is proposed and then simulation experiment is carried out. The simulation results verify that this strategy can restrain torque ripple well and the system has all right dynamic state and static state.
