In the field of ship-borne PMSM, there exists the sea wave fluctuations, external disturbances thus model uncertainties are always challenging the control design of ship-borne permanent magnet synchronous motors (PMSMs). To deal with this problem, a super-twisting extended state observer (SESO) is used in this paper to observe state variables accurately. Moreover, to solve the phase delay problem in active disturbance rejection control (ADRC), Taylor’s formula-based tracking differentiator (TTD) is applied in the proposed hybrid control strategy. With appropriate compensate of disturbance, denoted as super-twisting hybrid control, the controlled position signal can follow the reference with small tracking errors, also with improved dynamic performance. Simulation results show that the proposed super-twisting hybrid control has the better anti-disturbance and tracking performance compared with the traditional ADRC. Lastly, semi-physical experimental results further validate the effectiveness of the control strategy for ship-borne PMSMs.

船载永磁同步电机超扭转混合控制


在船载永磁同步电机领域，存在海浪波动、外界干扰等因素，模型不确定性一直困扰着船载永磁同步电机（PMSM）的控制设计。为了解决这个问题，本文使用超扭曲扩展状态观测器（SESO）来精确观测状态变量。此外，为了解决自抗扰控制（ADRC）中的相位延迟问题，在所提出的混合控制策略中应用了基于泰勒公式的跟踪微分器（TTD）。通过适当的扰动补偿，即超扭转混合控制，受控位置信号可以以较小的跟踪误差跟随参考值，并且具有改进的动态性能。仿真结果表明，与传统ADRC相比，所提出的超扭转混合控制具有更好的抗扰动和跟踪性能。最后，半物理实验结果进一步验证了船载永磁同步电机控制策略的有效性。
