【Abstract】 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.更多还原
