【Abstract】 In order to ensure that the three-phase inverter system can maintain good dynamic and steady state performance in the presence of different kinds of disturbances, a composite disturbance rejection control method based on disturbance observer is designed. Firstly, the mathematical model of three-phase inverter system with interference is established. Then, an anti-jamming control method of three-phase inverter based on the composite disturbance observer is designed, which can accurately estimate and compensate the load side abrupt disturbance and the input side periodic disturbance at the same time, and perform strict stability analysis of the closed-loop system. Meanwhile, simulations verify the effectiveness of the proposed method.更多还原
