【摘要】 针对电池电源逆变系统中的直流-直流变换器,提出了采用模糊控制和平均电流控制相结合的方法(称为模糊平均电流控制法)进行控制,并且使用了比常见的小信号平均分析法更为精确的大信号模型对系统进行建模分析。文章在系统模型的建立、控制方案的设计、参数整定等方面都做了详细的说明。针对一个电池电源系统实例,使用Matlab搭建平台和控制系统进行仿真分析。这种控制算法具有响应迅速,抗扰动能力强的优点,在仿真结果中也得到了证明。更多还原

【Abstract】 This paper describes a control method based on fuzzy logic control and average current-mode control(ACMC) for DC-DC converters in cell inverter system.A large-signal model is presented in this paper,which is more accurate than averaging small-signal model.Modeling,design and regulation processes are discussed in this paper.Matlab is used to build the plant and control system for an actual fuel cell system.By using this control strategy,the system can regulate the output voltage with a satisfactory subject to load changes.Simulation results also support the theoretical analysis.更多还原
