The invention discloses a permanent magnet motor variable scanning control system based on automatic disturbance rejection control. The control system adopts a speed-current q-d two-axis closed-loop control structure which comprises an active disturbance rejection control module, a first current controller, a second current controller, a first PARK inverse conversion module, a second PARK inverseconversion module, a CLARK conversion module, a space vector pulse width modulator (SVPWM), a three-phase inverter, and a speed and angle calculation module. The active disturbance rejection control module, the first current controller, the first PARK inverse conversion module, the space vector pulse width modulator (SVPWM) and the three-phase inverter form a connection link, and the first PARK inverse conversion module is also connected with the second current controller and the second PARK inverse conversion module. The second PARK inverse transform module is also connected with the CLARK transform module. In the va
