摘　　要：根据混合动力汽车对变换器的要求,设计了一种两相交错并联双向DC/DC变换器,减小了重量与体积,提高了系统的工作效率。分析了该变换器的工作原理,提出一种模糊控制与PID控制相结合的复合控制策略,并将其应用于两相交错并联双向DC/DC变换器的控制系统中。采用模糊控制可以很好地消除系统内部参数变化及外部干扰对控制效果的影响,增强系统的稳定性和鲁棒性,PID控制使得其控制器的调整更加灵活。最后,仿真和实验结果验证了理论分析的正确性。According to the requirements of the hybrid electric vehicle of the converter,this paper designs a two phase staggered parallel bidirectional DC/DC converter.It not only reduces the weight and volume,but also improves the work efficiency of the system.The working principle of the converter is analyzed.Then,this paper presents a fuzzy PID control strategy and uses it to the control system of the two phase staggered parallel bidirectional DC/DC converter.Fuzzy controller can well eliminate the influence of internal parameter variations and external disturbances on the system control,and also enhance the stability and robustness of the system,PID controller makes the controller adjust more flexible.Finally,the simulation and experimental results validate the correctness of theoretical analysis.
