摘要
基于模糊控制理论,结合非线性控制,提出了一种降压变换器的新型拓扑结构。该结构具有模糊控制策略的优点,且不用建立复杂的数学模型,控制方法简单,可使PWM开关变换器的输出电压,在有负载和电源电压干扰时,具有优良的动态响应。仿真和实验结果证明了该方法和结构的可行性和优越性。
Based on Fuzzy logic control and nonlinear control, a new structure of Buck DC/DC converter is proposed in this paper.With the strongpoint of fuzzy logic control,the new system can eliminate the effect of the large and small signal disturbances of the line voltage and the load on the output voltage of PWM DC/DC converters.Computer simulation and experiment verification of the described system was performed.
