Abstract

The second-order typical fast finite-time extended state observer (FFESO), third-order generalized FESO, and third-order augmented FFESO are adopted to directly estimate the motor speed and lumped disturbance, thereby enhancing the disturbance rejection and noise suppression properties of permanent magnet synchronous motor (PMSM) speed control systems. Although conventional linear extended state observer (ESO) has been proven to improve the anti-disturbance and robustness of motor speed control system, its estimation error can only converge asymptotically to an infinite region. In this brief, different speed control algorithms combining proportional control with different types of FFESOs are proposed. By introducing nonlinear terms into conventional ESO, the estimation accuracy of the proposed FFESOs can be greatly enhanced. Meanwhile, experimental results show a clearer analysis of the characteristics of FFESOs with different structures and orders.

利用不同阶快速有限时间扩展状态观测器改善PMSM速度控制系统的抗扰和噪声抑制性能

采用二阶典型快速有限时间扩展状态观测器（FFESO）、三阶广义扩展状态观测器（FESO）和三阶增广状态观测器（FFESO）直接估计电机转速和集总扰动，从而提高永磁同步电机（PMSM）调速系统的抗扰和噪声抑制性能。虽然传统的线性扩展状态观测器（ESO）已被证明可以提高电机调速系统的抗扰性和鲁棒性，但其估计误差只能渐近收敛到无限区域。本文提出了将比例控制与不同类型的ffeso相结合的速度控制算法。在常规ESO中引入非线性项，可以大大提高ffeso的估计精度。同时，实验结果更清晰地分析了不同结构和顺序的ffeso的特性。
