摘要/Abstract

摘要： 传统占空比预测转矩控制的目标函数包含一个权重系数,权重系数的选取繁琐且耗时。为了消除权重系数并提高稳态性能,提出一种双矢量无权重预测转矩控制方法。该方法将转矩误差和磁链误差转换到α,β坐标系下,构建以备选矢量到转矩误差直线和磁链误差圆的距离之和的目标函数,以消除权重系数。引入占空比控制,进一步减小转矩和磁链脉动。仿真与实验结果表明,该方法具有良好的控制性能。

Abstract: The cost function of traditional predictive torque control based on duty control contains a weighting factor, and the selection of weighting factor was cumbersome and time-consuming. In order to eliminate the weighting factor and improve the steady-state performance, a double vector predictive torque control without weighting factor was proposed. Torque error and flux error were converted to α,β in the coordinate system, and the cost function was constructed based on the sum of the distances from the candidate vector to the torque error line and the flux error circle so as to eliminate the weighting factor. On the basis, duty cycle control was introduced to further reduce torque and flux ripple. Simulation results show that the proposed method has good control performance.
