Buck converter based on One-cycle control and PD control

Buck circuit based on one-cycle control has fast dynamic tracking ability, good robustness and high-quality output waveforms, but this system has disadvantages in dynamic characteristics, such as too big overshoot, too long rising time, and so on. Based on engineering application, a PD controller is designed which was introduced to the original system, and a negative feedback is constructed to achieve dynamic compensation. The simulation results show that the dynamic characteristics of the system is highly improved.
