The Design of Fuzzy Internal Model PID Controller in High-frequency Switching Power Supply
Against the structure of the phase-shifted full-bridge switching power supply system and the complexity of traditional PID controller parameter adjustment,the full-bridge switching power dynamic small-signal mathematical model was established by using the state-space averaging method firstly,and the accuracy of which was verified by simulation;then an Internal Model PID Controller was designed based on the Internal Model design principle to reduce the number of adjustable parameters and the complexity of parameters adjustment;By introducing the Fuzzy algorithms,a fuzzy internal model-PID controller was designed to take into account the dynamic performance and robust performance,Finally simulation proves the effectiveness of the designed controller.
