摘要：

In this paper we propose a fuzzy optimization of the bang-bang control using a fuzzy controller in the feedback loop. The nonlinear characteristic of the fuzzy controller is designed to minimize the output voltage ripple of the buck switching voltage regulator. Feedback signal is output voltage error gain by a value which is nonlinear dependent by output voltage ripple. Comparing this feedback signal with a de offset level results the PWM command signal. The feasibility and effectiveness of this relative simple control method is shown by simulation. A comparison with the PI control method is included, too.
