Abstract
With the development of power system, routine PID controller could not satisfy the requirement of systemic dynamic and static performances. In this paper, in order to overcome the shortcoming of routine PID controller, a new kind of fuzzy-PID controller is designed (Bai et al., 2010). The new fuzzy-PID controller combines the advantages of routine PID controller and fuzzy logic controller (Dou et al., 2012). The mathematical model of synchronous excitation system and the architecture, principle and function of the fuzzy-PID controller are analyzed (Fu J., et al., 2014). And the application of the routine PID controller and fuzzy-PID controller in synchronous excitation system are studied with Simulink. The results show that the fuzzy-PID controller gives a better control performance and has reference value in the further applied research (Gan et al., 2015).
