开关磁阻电机转矩脉动抑制优化仿真
|
摘要
由于开关磁阻电机具有非线性和磁路饱和特点,转矩存在较大脉动,很难满足车用电机低脉动要求。合理的控制策略能更好的抑制转矩脉动。针对基于转矩分配函数的直接瞬时转矩控制中相电流瞬时尖峰值过大的问题,提出了一种应用转矩滞环和电流滞环的双滞环控制方案,达到了抑制相电流值瞬间增大、换相过程中转矩脉动更小的控制目标。在建立开关磁阻电机调速系统的传统控制、直接瞬时转矩控制和双滞环控制的MATLAB/Simulink模型基础上,对6/4极的三相开关磁阻电机进行了仿真。分别从相电流、转速和合成转矩三个方面对比了传统CCC控制、转矩滞环控制和双滞环控制的控制效果,仿真结果证明双滞环控制有更优的控制效果。
This article proposes a control scheme with double hysteresis applying torque hysteresis and current hysteresis,and achieves the control objectives of suppressing instant enlargement of value of phase current and reducing torque pulsation during commutation process. Firstly,based on MATLAB/Simulink we built models for traditional control,direct instantaneous torque control,and double hysteresis control of speed regulating system of switched reluctance motor. On that basis,we simulated three-phase switch reluctance motor of 6/4 pole. We compared the control effect of traditional CCC control,torque hysteresis control,and double hysteresis control from three aspects of phase current,rotation rate,and resultant torque. Simulation results show that the double hysteresis control has better control effect.
