Abstract

In order to improve the quality of power that the phase-shifted full-bridge DC/DC boost circuit supply to the microgrid and the safety and reliability of its operation, fuzzy PID control method is used to achieve phase-shift control of the main circuit in the paper. The output DC voltage is controlled by adjusting the phase-shifting angle between the leading-leg and the lagging-leg. According to the response of the system, fuzzy inference is used to change the PID parameters in real time so that the control effect of the system can be optimized. Firstly, the modeling and simulation are performed by MATLAB/Simulink to verify the superiority of fuzzy PID over traditional PID control methods. Then the TMS320F28335 DSP chip is used to program for the hardware implementation of the control strategy, and the feasibility of which is verified by the experimental waveform. Finally, the experiment shows that this control technology achieves the effective control of the DC/DC boost circuit, which has good dynamic and steady state performance and the operation quality of the equipment is improved greatly. It has a certain promotion value.
