摘要

基于全阶滑模观测器的凸极永磁同步风力发电机无速度传感器控制可以通过提高滑模增益来提高系统的鲁棒性

但提高滑模增益会放大滑模噪声。为了解决这个矛盾

文中提出了有效反电动势的概念

并基于有效反电动势的概念设计了一种全阶状态滑模观测器

分析了该全阶状态滑模观测器的滑模抖振抑制特性和转子位置估计对转速估计误差的鲁棒性。与全阶滑模观测器相比

所建立的全阶状态滑模观测器在不放大滑模噪声的前提下

可进一步提高转子位置估计对转速估计误差的鲁棒性。实验结果表明

该方法可实现稳定的无速度传感器控制

具有良好的动稳态特性

转子位置估计对转速估计误差具有更强的鲁棒性。

Abstract

The speed sensorless control for salient permanent magnet synchronous wind generators based on full-order sliding mode observer can improve the robustness by improving the sliding mode gain. However

the sliding mode chattering will be magnified if the gain is too large. In order to solve this problem

this paper proposes the concept of active back electromotive force (ABEMF). Furthermore

a full-order state and sliding mode observer is designed based on this concept. The characteristics of sliding mode chattering suppression and the robustness of the estimated rotor position for the estimated speed error are analyzed. Compared with the full-order sliding mode observer

the proposed full-order state and sliding mode observer can further improve the system robustness with the sliding mode chattering unchanged. The experimental results show that the proposed algorithm can realize stable sensorless operation and has good dynamic and steady-state characteristics. The robustness of the estimated rotor position for the estimated speed error is stronger.
