摘　　要：为提升卫星电源蓄电池充电调节器(BCR)的工作性能,基于Lyapunov稳定性理论,提出了一种新型的BCR控制方法。首先根据BCR的工作机理,获得了系统的非线性数学模型,然后通过构造系统的Lyapunov函数,设计适当的控制律,不仅保证了闭环系统的大范围稳定,而且实现了母线对蓄电池充电时母线电压的有效调节。最后,采用MATLAB软件进行仿真分析,验证了所提控制方法的可行性和有效性。仿真结果表明,基于Lyapunov函数的新型控制方法具有良好的母线电压调节性能和较强的抗负载扰动能力。In order to improve the performance of the battery charge regulator(BCR)for satellite power systems,a novel BCR control method was proposed based on the Lyapunov stability theory.Firstly,a nonlinear mathematic model was obtained according to the BCR working mechanism.An appropriate control law was designed by constructing the system Lyapunov function,which not only ensured the wide-range stability of the closed-loop system,but also realized the effective regulation of the bus voltage when the battery was charged by the bus.Finally,the simulation analysis was carried out with MATLAB,and the feasibility and effectiveness of the proposed control method were verified.The simulation results show that the novel control method based on the Lyapunov function has good bus voltage regulation performance and strong anti-load disturbance ability.
