Summary:Sliding mode controller (SMC) has good disturbance rejection ability. It can replace the PI controller in permanent magnet synchronous motor (PMSM) control system to enhance the performance. However, it exists the chattering problem, which may cause the system instable. An integrated position-velocity-current loop sliding mode active disturbance rejection controller (PSM-ADRC) is proposed to suppress the chattering. So as to solve the puzzle of reliability reduction resulted by position sensors, a new sliding mode observer (SMO) is utilized, whose reaching rate is improved by the segmentation power function. The simulation results show the superiority of the sensorless control system of PMSM based on double sliding mode active disturbance rejection controller.
