摘　　要：针对多电飞机负载的大功率突变、能量回馈以及恒功率特性,考虑飞机直流母线负载鲁棒稳定问题,提出一种新颖的基于VIENNA整流器的直流母线供电方法。考虑到外界干扰和未建模动态对系统的影响,利用干扰观测器,结合滑模控制方法,实现了对状态的观测和对干扰的估计,获得了适用于VIENNA整流器的滑模控制器,保证了直流母线鲁棒稳定。仿真结果表明:相比于传统供电方法,所提供电方法提高了母线电压响应速度,增强了系统鲁棒性。Considering the high-power mutation,energy feedback and constant power characteristic of More-electric aircraft loads,a novel DC power supply method based on VIENNA rectifier was proposed to deal with the robust stability problem of DC loads.Considering the influence of external disturbance and unmodeled dynamics,sliding mode controller combining disturbance observer was designed to observe the state and estimate the disturbance so the robust stability of DC power bus can be achieved.Simulation results show that the proposed method improves the response speed and the robustness of the DC power system.
