摘要
针对5相开关磁阻电机进行了直接转矩控制策略的分析与研究,提出了5相开关磁阻电机10个有效电压空间矢量的构造原则,通过5/2变换得到合成定子磁链,分析了在定子磁链空间的10个区域内,如何选择合适的电压矢量来快速达到磁链和转矩按给定变化的要求,以保证磁链和转矩基本不变,并给出了5相开关磁阻电机直接转矩控制的开关表。对5相开关磁阻电机直接转矩控制进行了仿真,仿真结果表明,这种控制策略能够有效地抑制转矩波动,系统动静态特性良好。
The direct torque control strategy for five-phase switched reluctance motor was researched andanalyzed.The structure principle about ten effective voltage space vectors for five-phase switched reluctance motor wasproposed.The stator flux space in the ten regions,how to select the appropriate voltage vector to quickly reach flux andtorque requirements of a given change in order to ensure substantially constant flux and torque was analyzed,and givedfive phase switched reluctance motor direct torque control switch table.The simulation results of the five-phaseswitched reluctance motor direct torque control show that this control strategy can effectively suppress torquefluctuation,system has good static and dynamic characteristics.
