基于自适应二阶扰动观测器的永磁同步电机无位置传感器驱动策略

In this article, an adaptive second-order disturbance observer (SODO)-based position sensorless drive strategy for permanent magnet synchronous motor (PMSM) considering disturbance compensation is proposed. To achieve finite time observation of disturbance in the case of the boundaries of the system disturbance and its derivative are unknown, an adaptive SODO is put forward first. Under the premis...
