摘要
利用状态空间平均模型推导了带有Duck变换器并具有定电压跟踪功能(CVT)的光伏系统模型,求出了该系统的闭环传递函数,应用罗斯判据确定了控制器参数的范圈。最后对直流和交流光伏水泵进行校正,证明该方法具有良好的应用效果。
In this paper the state-space average model is used to infer the model of the PV system with Duck converter and constant voltage tracker (GVT). The close loop transfer function of the GVT PV system is deduced. The Routh-Hurwitz criterion is employed in calculation of the controller parameter. The method is applied to rectify the CVT PV water pump system, and its effectiveness in application is proved.
