Abstract

A systematic method was introduced to design a full-scale fuzzy PID controller for power system stability control. The proposed controller uses the incremental form of a conventional PID controller as its underlying structure. To show the effectiveness of this method a form of full-scale fuzzy PID controller is designed. The rule-generated function is used to generate the rule base. The parameters of a conventional PID controller, which can be achieved by several well-known methods in control theory such as Ziegler-Nichols, Cohen-Cool and the genetic algorithm, make it possible to simplify the design process, as is desirable from an industrial point of view. One advantage of the new full-scale fuzzy PID controller is that it has the same structure and simplicity of its conventional counterparts but with more effectiveness and robustness. In order to illustrate the effectiveness of this controller a SVC-based stabiliser is designed using the proposed fuzzy PID controller.
