摘要

The unified dynamical model of DC-DC buck converter is set up, and then two sliding mode controllers are introduced called conventional sliding mode controller and sliding mode proportional integral derivative (PID) controller. The stability are analyzed for the DC-DC converter system controlled by the sliding mode PID, and the optimum sliding mode PID parameters are determined. Finally, the system simulation is implemented and simulation results validate that the sliding mode PID controlled DC-DC buck converter has better dynamic and static performance than the system controlled by the conventional sliding mode controller.
