一种用于表贴式永磁同步电机无传感器控制的增益自适应高阶终端滑模观测器

In this article, a gain-adaptive (GA) high-order terminal sliding mode observer (HOTSMO) is designed for back-electromotive force (back-EMF) estimation in the sensorless control of permanent magnet synchronous motors. The proposed observer features an adaptive gain mechanism that dynamically adjusts the sliding mode gain coefficient based on the system state. During the reaching phase with large o...
