摘　　要：战时,航母上两部主力弹射储能系统可能遭受打击,进而使其蓄电池组部分遭受损坏。依靠两者之间功率动态平衡建立的交替弹射时序可能发生紊乱。针对此问题,提出了基于电磁弹射系统耦合的弹射时序再恢复控制策略。首先,建立了包含蓄电池、超级电容器(super capacitor, SC)、直线电机(line motor, LM)及耦合装置的电磁弹射系统耦合模型。其次,在分析弹射系统动态特性的基础上,提出了充放电功率优化策略。即通过协调互联装置与储能控制,在失衡的非完备状态初始条件下,实现两侧系统在各自弹射周期内功率交替性动态平衡,进而恢复正常的弹射时序。并针对动态充放电过程中的蓄电池单侧耗尽问题,提出了基于荷电状态(state of charge, SOC)均衡的自适应下垂控制方法。最后利用Matlab/Simulink软件进行建模仿真,验证了所提策略在实现交替弹射时序再恢复及避免蓄电池单侧耗尽方面的有效性和优越性。In wartime,the two main ejection energy storage systems on an aircraft carrier may be hit,and then the battery pack will be partially damaged.The timing of alternating ejections,established by the dynamic balance of power between the two,can be disrupted.To solve this problem,a related ejection timing re-recovery control strategy based on the coupling of the electromagnetic ejection system is proposed.First,a coupling model of the electromagnetic ejection system including a battery,a supercapacitor(SC),a line motor(LM)and a coupling device is established.Secondly,based on the analysis of the dynamic characteristics of the ejection system,an optimization strategy for charge-discharge power is proposed.That is,by coordinating the interconnection device and energy storage control,in the initial condition of the unbalanced incomplete state,the power alternating dynamic balance of the two systems in their respective ejection cycles is realized,and then the normal ejection timing is restored.To solve the problem of one-sided depletion of the battery in the process of dynamic charging and discharging,an adaptive droop control method based on state of charge(SOC)equilibrium is proposed.Finally,Matlab/Simulink software is used for modeling and simulation,and this verifies the effectiveness and superiority of the proposed strategy in realizing alternating ejection timing re-recovery and avoiding unilateral depletion of the battery.
