基于谐波效应补偿的对称六相与三相PMSM串联系统解耦控制研究
|
摘要
以凸极式对称六相与三相PMSM串联系统为研究对象,针对低次空间谐波导致串联系统不解耦问题,以电机含有空间2次谐波为例,建立起考虑2次谐波耦合的串联系统数学模型,设计了基于谐波效应补偿的对称六相与三相PMSM串联系统解耦控制策略。根据串联系统的数学模型和两台电机的实时运行状态,在两台电机各自的转矩控制环节分别进行补偿。仿真结果表明,所提控制策略消除了两台电机转矩上的脉动量,两台电机的运行状态可以独立调节、互不影响。
The six-phase and three-phase PMSM series-connected system with salient-pole was studied in this paper. As for the coupling relationship between the two motors caused by spatical harmonics, taking the 2~(nd) spatial harmonic for example, mathematical model of the series-connected system considering the 2~(nd) spatical harmonic was derived. A decoupling control strategy based on harmonic effect compensation was proposed. The magnitude pulsating torque was firstly calculated according to the mathematical model and the operation state of the two motors to eliminate the torque pulsation. Simulation result shows that the proposed control strategy finally eliminated the torque ripple and the operation state of the two motors could be adjusted independently without affecting each other.
