The utility model relates to a dual loop control system based on active disturbance rejection. The dual loop control system based on the active disturbance rejection includes a direct current voltage source, an inverter, a controller system, and a filter circuit; the controller system includes a space vector pulse width modulation circuit, an active disturbance rejection voltage controller and a current controller; the space vector pulse width modulation circuit modulates and controls the inverter; the direct current voltage source is converted by the inverter to a three-phase alternating current; the three-phase alternating current is processed by a filter to filter out higher harmonics and is used to supply power to a load; a front-end voltage signal and a given voltage signal of the load are inputted to the active disturbance rejection voltage controller; a capacitor current signal in the filter and an output of the active disturbance rejection voltage controller are inputted into the current controller; and a controllable sinusoidal modulation signal of outputted by the current controller is transmitted to the inverter through the space vector pulse width modulation circuit. Compared with a conventional PI control, the active disturbance rejection control has the strong anti-interference ability, and can maintain the stable operation of the microgrid in the islanding mode.
