基于电机转矩波动控制的车内噪声优化研究
|
摘要
电机控制策略对整车的NVH性能存在不同程度的影响,通过对电机转矩波动进行控制可以改善电机输出转矩的平顺性,进而提高整车的舒适性。通过对影响电机转矩波动的因素进行分析,并对电机转矩波动控制策略进行优化,达到优化车内噪声的目的,为解决类似问题提供一种思路及方法。
The motor control strategy has different influences on the NVH performance of the whole vehicle. By controlling the torque ripple of the motor,the smoothness of the motor output torque can be improved,thus improving the comfort of the vehicle. This paper analyzes the factors affecting the torque ripple of the motor,and optimizes the control strategy of the torque ripple of the motor,so as to optimize the noise in the vehicle and provide a way for solving similar problems.
