N2 - In view of the stratospheric airship application requirements on energy storage and management system, based on the topology of DC/DC converter main circuit, the composite PI controller is designed to realize respective control with the Boost mode and Buck mode. Furthermore, limit stop integration method is proposed to achieve a buck-boost complex DC/DC converter boost with effective switching buck. Then, with the MATLAB Control System Toolbox design model, the composite PI controller design and a simulation is accomplished. According to the simulation model, the structure and parameters of the controller to the system can be easily adjusted. Finally, by using the average large-signal switching mathematical model to create subcircuit in place of the actual circuit model, the whole circuit model of the DC/DC converter is constructed with MATLAB, and then, from the analysis of simulation results, it’s proved that the method can shorten the simulation time and obtain better convergence of the target.
