摘　　要：提出一种逆变电源无差拍控制方法和传统PI控制方法相结合的复合控制方法在理论分析的基础上利用MATLAB/SIMULINK建立相应的逆变电源系统模型,在仿真过程中确定PI控制器参数值,从而完成整个控制器的设计在不同负载情况下和主电路滤波器参数发生变化时的仿真结果表明设计的逆变电源系统抗负载扰动能力强,对参数具有一定的鲁棒性。A compound control scheme in the inverter system, which combines the deadbeal control method and the conventional proportional and integral (PI) control method is proposed. Based on the theory analysis, a model of the inverter system was built up using MATLAB/SIMULINK. Then simulations are performed to determinate the parameters of the PI controller, thus the whole design of the controller is completed. Simulation results under the variety of the loads and the change of the filter parameters in the main circuit, shows that the designed inverter system has a strong capalnlity to resist the load disturbance. is robust to the filter parameters, and traces the smusoidal reference signal. The proposed control scheme offers another method to parallel the inverters.
