Bibliography:In view of the main circuit 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. And then, on the basis of the internal model design principle, an internal model PID controller was designed to reduce the number of adjustable parameters and the complexity of parameters adjustment. By introdu- cing the fuzzy algorithms, a fuzzy internal model-PID controller was designed to take into account the dynamic per- formance and robust performance. Finally, simulation proves the effectiveness of the designed controller.
