Abstract :
A controller is designed to drive buck DC power converter systems based on smooth sliding mode control and backstepping design method. The controller can limitly track the reference output voltage trajectory and make the tracking error arbitrarily small, at the same time considering the parameter uncertainty of load resistance and the attenuation of electrical source. It belongs to practice tracking. The method makes the best of the systematization and structurization in the backstepping design, the application of smooth sliding mode makes the controlled system have good robustness. The effectiveness of the proposed control scheme is verified by the simulation and the controller fully satisfies the demand of engineering.
