摘要

传统的无轴承永磁薄片电机通过径向位移的闭环控制来间接实现悬浮力稳定控制，当薄片转子受到径向干扰时，由于悬浮力处于开环状态，悬浮力控制的精度和动态响应性能将受到限制。且悬浮力控制中所需的相位信息是需要在准确获得转子角度的基础上才能得到，因此增加了电机控制系统复杂性。为了克服以往悬浮力控制的上述不足，本文在推导了无轴承永磁薄片电机悬浮力变化量和悬浮力绕组磁链变化量之间关系的基础上，提出了径向悬浮力和径向位移的双闭环补偿控制策略，采用电压-电流模型对转矩绕组气隙磁链进行辨识，使得电机控制的灵活性大大增加。仿真和实验结果表明：所提出的悬浮力控制方法能够提高悬浮力控制精度和动态响应性能，系统抗干扰能力强，且具有良好的动、静态性能。

Abstract

In the traditional bearingless permanent magnet slice motor (BPMSM), radial displacement’s closed loop control was used to realize indirectly the stable control of suspension force. If the motor’s rotor is subjected to radial interferences, the accuracy of suspension force control and its dynamic performance are restricted. Besides, the phase information needed for suspension force control relies on accurate measurement of rotor position to make the control system be more complex. In order to solve the problems mentioned above, here the relationship between suspension force changes and flux linkage changes of suspension force winding in a BPMSM was deduced. Then the double-closed loop compensation control strategy for radial suspension force and radial displacement was proposed. The flux linkage of torque winding was identified based on the voltage-current model to improve greatly the motor control flexibility. The simulation and test results showed that the proposed suspension force control method can improve the control accuracy and dynamic performance of suspension force; the control system has a strong anti-disturbance ability, good static and dynamic performances.
