This paper investigates three-phase two-level VSI hysteresis-based Model Predictive Control (MPC) for permanent magnet synchronous machines with different current error shapes. To limit the motor current harmonics and prevent overheating of the magnets, motor filters (mostly LC filters) are often used. The hysteresis-based MPC is investigated to provide high dynamic performance and limit the size of the filter. To compensate the resonance introduced by the LC filter and to improve system efficiency, a virtual resistor active damping strategy is implemented. To avoid additional sensors, the filter states are determined by a Luenberger Observer. However, up to now these strategies have never been investigated together with MPC and different current error shapes for motor applications. Simulation results for the different strategies prove the performance efficiency and experimental tests verify the results in a laboratory environment.

考虑不同误差形状的LC滤波器PMSM的迟滞模型预测电流控制

本文研究了三相两级基于VSI磁滞的模型预测控制（MPC），用于具有不同电流误差形状的永磁同步电机。为了限制电动机电流谐波并防止磁体过热，通常使用电动机滤波器（主要是LC滤波器）。研究了基于磁滞的MPC，以提供高动态性能并限制滤波器的尺寸。为了补偿LC滤波器引入的谐振并提高系统效率，实施了虚拟电阻器主动阻尼策略。为避免额外的传感器，滤波器状态由Luenberger观察者确定。但是，到目前为止，尚未针对电机应用将这些策略与MPC和不同的电流误差形状一起进行研究。
