本文提出了一种基于轴加速度转矩的高性能逆变控制方法。传统的过调制方法既有优点也有缺点。该方法从加速转矩指令和电压饱和导致的漏电压考虑电机驱动状态，自动判断是否需要过调制。因此，该方法结合了使用过调制的优点和不使用过调制的优点，获得了瞬态快速响应和稳态总谐波畸变小的特性。实验结果验证了所提出的高性能逆变控制方法的有效性。
This paper proposes a high-performance inverter control method based on the shaft acceleration torque. The conventional overmodulation method has both advantages and disadvantages. The proposed method considers the motor driving condition from the acceleration torque command and the omitted voltage caused by voltage saturation and automatically judges whether overmodulation should be used. Therefore, this method combines the advantages of using overmodulation and the advantages of not using overmodulation and obtains both a quick speed response in the transient state and a small value of total harmonic distortion in the steady state. The experimental results verify the effectiveness of the proposed high-performance inverter control method.
