研究静止同步补偿器的非线性鲁棒控制器的设计。给出静止同步补偿器的动态模型,并针对模型的不确定因素及非线性,分两步设计系统控制器。首先应用微分几何方法对模型线性化,得到系统的精确线性化模型。然后针对上述线性化模型设计系统的鲁棒H∞控制器。应用线性化方法中的坐标变换和状态反馈得到静止同步补偿器的鲁棒控制。最后给出一个仿真研究结果。

Robust controller for static synchronous compensator (STATCOM) is designed. Dynamic model of STATCOM is given, which contains uncertainty and is nonlinear. For this feature, the design of the controller consists of two steps which are linearization of the model based on differential geometry and H ∞ controller design for linearized model. The robust controller for STATCOM is obtained by coordinate transformation and state feedback and the results of simulation example are given.
