摘要
针对一种具有优良电气特性的新型Buck-Boost矩阵变换器(BBMC)采用基于模糊PI的双闭环控制策略进行控制。阐述了该变换器的基本原理,研究了基于模糊PI的双闭环控制的具体设计方法。并采用MATLAB对其控制效果进行了仿真验证。结果表明:当BBMC输入侧电压发生突变时,模糊控制器能有效调节PI参数,使输出电压有效的跟随输入电压的变化而变化,从而系统迅速达到稳定。
According to a new Buck-Boost matrix converter （BBMC） having excellent electrical performance,uses the double closed loop control strategy based on fuzzy PI. This paper expounds the basic principle of the converter, studies the design method of double closed loop control based on fuzzy PI, and uses the MATLAB for the simulation of the control effect. The results show that, when the BBMC input voltage change, the fuzzy controller can effectively adjust the PI parameters, making the change of the output voltage effectively follow the change of the input voltage, thus the system rapidly reaches stable.
