A Fuzzy PID Controlling Method Based on URC Used in Phase Shifting Full Bridge

Phase Shifting Full Bridge(PSFB) has a nonlinear character,and traditional fuzzy PID controller may have problems as rule explosion,which effects on real time reflection.A fuzzy PID controller based on Union Rule Configuration(URC) is proposed in this paper,and it decreases the logical rules sharply.According to Matlab simulation,the stabilization time of the proposed controlling method is less than that of the traditional method.That means the proposed control method may be more suitable for the embedded systems.
