Abstract

In this study, an experimental approach for the weighting factor design of the predictive torque control of an induction motor (IM) is presented. The weighting factor is set to the value which yields a low total harmonic distortion (THD) figure in the phase currents. Then, this optimized value is dynamically adjusted with respect to the speed error term, which is defined as the magnitude of difference between the commanded speed and the actual speed. By doing so, superior transient performance is achieved without sacrificing steady-state THD values. The presented approach for dynamically adjusted weighting factor is tested on a two-pole, 500 W IM, driven by a two-level voltage source inverter (2L-VSI), via finite control set model predictive control (FCS-MPC). Experimental results show the effectiveness of the proposed method: by the adoption of dynamic lambda approach, speed reversal time from -3000 rpm to +3000 rpm is decreased by 38% under the same controller structure and settings.
感应电机预测转矩控制中动态重配置权重因子的实验调谐与设计准则
本文提出了一种用于感应电机预测转矩控制的权重因子设计的实验方法。将权重因子设置为在相电流中产生低总谐波失真(THD)图的值。然后,根据速度误差项对该优化值进行动态调整,速度误差项定义为命令速度与实际速度之差的大小。通过这样做,在不牺牲稳态THD值的情况下实现了优越的瞬态性能。通过有限控制集模型预测控制(FCS-MPC),在双电平电压源逆变器(2L-VSI)驱动的500 W双极IM上对所提出的动态调整权重因子的方法进行了试验。实验结果表明了该方法的有效性:采用动态lambda方法,在相同的控制器结构和设置下,从-3000转到+3000转的速度反转时间减少了38%。
