无轴承永磁薄片电机驱动的液体泵在复杂的流体负载环境下对电机悬浮性能提出了更高的要求。针对该型电机模型难以准确获得、复杂流体负载影响电机悬浮性能问题，提出了一种基于电磁力建模与扰动补偿的转子径向悬浮性能改进控制策略。首先，基于麦克斯韦张量法，建立了包含主动悬浮力分量和偏心磁拉力分量的转子径向悬浮力解析模型；接着，通过线性扩张状态观测器观测未建模部分；然后，从补偿偏心磁拉力和补偿未建模部分的角度，重构悬浮绕组电流，构建相应的悬浮控制子系统；最后，通过实验验证了所提控制策略的有效性。

The liquid pump driven by a bearingless permanent magnet slice motor has higher requirements on the motor suspension performance in a complex fluid load environment. Aimed at the problems that the motor model is difficult to obtain accurately and the complex fluid load affects the motor suspension performance, an improved control strategy for the rotor radial suspension performance based on electromagnetic force modeling and disturbance compensation is proposed. First, based on the Maxwell tensor method, an analytical model of rotor radial suspension force including active suspension force component and eccentric magnetic tension component is established. Second, the unmodelled part is observed by a linear extended state observer. Third, from the aspect of compensating the eccentric magnetic tension and compensating the unmodeled part, the suspension winding current is reconstructed, and the corresponding suspension control subsystem is constructed. Finally, the effectiveness of the proposed control strategy was verified by experimental results.
