To improve noise and vibration of Electric Power Steering (EPS) system, we focus on the reduction of the sixth‐order radial force of an EPS motor by regulating its harmonic current. Because an EPS system is operated in a wide speed range, a reduction method is required to work even for dynamic motor speed. In this article, we introduce our method and report its test result to show the reduction of sixth‐order radial vibration of an EPS motor.

谐波电流控制降低六阶径向力及其在EPS电动机中的应用

为了改善电动助力转向（EPS）系统的噪声和振动，我们着重于通过调节其谐波电流来减小EPS电机的六阶径向力。由于EPS系统在较宽的速度范围内运行，因此即使在动态电动机转速下也需要使用减速方法。在本文中，我们介绍了我们的方法并报告了其测试结果，以显示EPS电机的六阶径向振动的减小。
