宽输入电压双有源桥变换器模糊自抗扰控制策略
Fuzzy active disturbance rejection control strategy for dual active bridge converters with wide input voltage
摘要
Abstract
We propose an optimal control strategy of dual active bridge(DAB)DC-DC converter suitable for wide input voltage for the characteristics of voltage diversity of military portable energy storage equipment.First,the mathematical model of each state of extended phase shift control is analyzed,and the small signal model of DAB converter is derived.Then,the simplified active disturbance rejection controller is connected to the voltage loop,and the fuzzy neural network algorithm is combined to optimize the controller parameters online to achieve the wide input voltage characteristics of DAB converter.Finally,a set of 500 W experimental prototype is built.Our results show the optimized control strategy enables the DAB converter to achieve better input voltage adaptability.Moreover,the input voltage range is improved from the original 40～60 V to 36～96 V and the response time is less than 5 ms,which improves the system's dynamic response capability.关键词
