电动车用永磁无刷电机转矩脉动的控制技术

无刷直流电机（BLDCM）是一种多变量和非线性的控制系统，针对永磁无刷电动机转矩脉动大、低速运行时噪声明显等主要问题，提出的自适应模糊控制器，可以克服未建模参数的影响，保证鲁棒性。该方法结合了换相电流预测控制和直流母线负电流消除特性，有效抑制了换相转矩脉动。通过仿真和实验验证了所述方法的正确性。

Techniques on Torque Ripple Control of Brushless DC Motor for Mini-Battery Electric Vehicle

The brushless DC motor is a multi-variable and non-linear system. Against the torque ripple and violent noise during low speed running by the permanent brushless DC motor, an auto-tuning method for fuzzy logic controller based on genetic algorithm (GA) was presented. In this paper, the fuzzy control method suppressed the influence by the un-modeling parameters and ensured the robustness. In the proposed method, commutation current prediction and the negative DC current elimination was used to suppress the c...
