The Design of an SVC Intelligent Variable Structure Controller

By imitating the intelligence of humans, a design method for an SVC variable structure controller is proposed based on the nonlinear variable structure control theory. The system operation features are extracted and used to judge the operating state and then give the control strategy. The decision procedure is independent of the structure of network and the working point of the system. The control law has good robustness. The application of the intelligence control strategy enables the state variables to tend to approach a sliding plane according to the control law predesigned. The results of computer simulation show that the controller proposed has improved the system stability as compared with that using a conventional SVC controller.
