永磁同步电机的控制存在速度控制、电流控制、无位置传感器控制等问题，需要进行控制增益设计。通常，需要考虑稳定性和响应性来设计控制增益，并且已经对此进行了各种研究。本文结合闭环传递函数的极点配置分析和考虑实际位置与估计位置之差的轴向误差的稳定性判断，分析了三种控制方式的控制带对稳定性的影响，讨论了保证结果的各控制带之间的关系。
For the control of permanent magnet synchronous motors, speed control, current control, sensorless control exist, and control gain design is required. In general, the control gain needs to be designed in consideration of stability and responsibility, and various researches have been conducted on this. In this paper, the influence of the control band of the three types of control on the stability is analyzed by combining the analysis of the pole placement of the closed-loop transfer function and stability judgment considering the axial error which is the difference between the actual position and the estimated position, the relationship between each control band that can secure the results is discussed.
