Torque ripple reduction of Brushless DC Motors (BLDCs) is an interesting subject in variable speed AC drives. In this paper at first, a mathematical expression for torque ripple harmonics is obtained. Then for a non-ideal BLDC motor with known harmonic contents of back-EMF, calculation of desired reference current amplitudes, which are required to eliminate some selected harmonics of torque ripple, are reviewed. In order to inject the reference harmonic currents to the motor windings, an Adaptive Input-Output Feedback Linearization (AIOFBL) control is proposed, which generates the reference voltages for three phases voltage source inverter in stationary reference frame. Experimental results are presented to show the capability and validity of the proposed control method and are compared with the vector control in Multi-Reference Frame (MRF) and Pseudo-Vector Control (P-VC) method results.
无刷直流电机（BLDC）的转矩脉动抑制是变速交流传动领域一个有趣的课题。本文首先得到了转矩脉动谐波的数学表达式。然后针对反电动势谐波含量已知的非理想无刷直流电机，回顾了消除转矩脉动中某些选定谐波所需的期望参考电流幅值的计算方法。为了将参考谐波电流注入电机绕组，提出了一种自适应输入-输出反馈线性化（AIOFBL）控制方法，该方法在静止参考系中为三相电压源逆变器生成参考电压。给出了实验结果，以表明所提控制方法的性能和有效性，并与多参考系（MRF）中的矢量控制和伪矢量控制（P-VC）方法的结果进行了比较。
