Abstract

To enhance the suppression performance of a permanent magnet synchronous motor (PMSM) in an electric propulsion system against both periodic and aperiodic disturbances, this paper proposes a quasi-resonant-controller-based cascaded linear active disturbance rejection control strategy (QRC-CLADRC) applied to the speed loop. The method adopts a cascaded linear extended state observer (CLESO) structure, in which the front-stage linear extended state observer (LESO) first processes the dominant disturbances, providing the subsequent stage with an initially “purified” state estimation. The back-stage LESO further eliminates the residual disturbances based on the compensation from the front stage. Moreover, a quasi-resonant controller (QRC) is embedded into the back-stage LESO to improve suppression of periodic speed fluctuations. A linear state error feedback control (LSEFC) mechanism is then designed to compensate for the estimated disturbances, thereby reducing speed ripple. The disturbance estimation performance, stability, and disturbance rejection capability of the system are theoretically analyzed. Finally, the effectiveness and superiority of the proposed method are validated on a 300-W electric propulsion experimental bench.

一种新型的电力推进系统速度控制，增强了对周期和非周期扰动的抑制

为了提高电力推进系统中永磁同步电动机（PMSM）对周期和非周期扰动的抑制性能，提出了一种基于准谐振控制器的级联线性自抗扰控制策略（QRC-CLADRC）。该方法采用级联线性扩展状态观测器（CLESO）结构，其中前级线性扩展状态观测器（LESO）首先处理主导扰动，为后级提供初始“纯化”状态估计。后级LESO在前级补偿的基础上进一步消除了残差干扰。此外，在后台LESO中嵌入准谐振控制器（QRC），以改善对周期性速度波动的抑制。然后设计线性状态误差反馈控制（LSEFC）机制来补偿估计的干扰，从而减少速度纹波。从理论上分析了系统的干扰估计性能、稳定性和抗干扰能力。最后，在300w电力推进试验台上验证了该方法的有效性和优越性。
