Design of DC-DC converter based on improved PID algorithm

As the core component of switching power supply, the DC-DC converter is widely used in aerospace power supply systems, power systems, and other fields, and its comprehensive performance is especially important for the reliability of switching power supply. The genetic algorithm and PID control algorithm are combined to overcome the limitation of relying on expert experience to adjust the PID control parameters and achieve the optimal control strategy of the DC-DC converter. Finally, the system control performance is simulated and comparatively analyzed by using Matlab, and the results show that the optimized PID control by the genetic algorithm is feasible and effective, and the control effect on the DC-DC converter is more significant.
