摘要
为改善传统有源滤波控制需要将非线性系统线性化的问题,研究了一种基于微分平坦理论的直接功率控制.在αβ坐标系下建立带有源电力滤波器的12脉波整流电路电压和功率的数学模型,通过前馈控制和非线性误差反馈补偿设计控制器,在MATLAB 2016a/Simulink中进行仿真验证.仿真结果表明:所提出的理论控制策略是有效的,直流侧电压有较好的稳定性,功率跟踪性良好,鲁棒性好.
In order to improve the traditional active filter control,a direct power control based on the differential flatness theory is studied. In the alpha beta coordinate system,the mathematical model with a source of power filter 12 pulse rectifier circuit voltage and power is established. The controller is designed through feedforward control and nonlinear error feedback compensation. The simulation results in the MATLAB 2016 a/Simulink show that the proposed theoretical control strategy is effective,the DC side voltage has good stability,good power tracking and good robustness.
