Induction generator is simple in structure and low in cost. Direct torque control is used to achieve the rapid response of induction motor electromagnetic torque and has good dynamic effect and simple control structure, but it is difficult to achieve satisfactory results considering that the method is easily affected by uncertain factors such as stator resistance parameter variation, load mutation and speed disturbance. Therefore an active disturbance rejection controller is applied to control DC voltage to reduce negative impact of unknown disturbances in the model that was built by observing and compensating the total disturbances. The results show that the scheme has the features of rapid response, robustness, and outputs dc voltage stably.
