针对重复使用运载器(reusable launch vehicle,RLV)在末端区域能量管理(terminal area energy management, TAEM)段中存在的多约束问题,提出了一种 TAEM段约束控制策略。通过俯仰角速率控制 TAEM内回路,提高了控制系统的稳定性;设计了迎角和过载约束控制回路,在此基础上,采用动态约束的思想,实时进行约束控制回路的切换,保证了飞行的安全;并分别在常规控制策略和约束控制策略2种情况下进行了仿真验证。仿真结果证明:采用约束控制策略可以保证RLV迎角和过载不超出限制,可以保证最终的安全着陆。
針對重複使用運載器(reusable launch vehicle,RLV)在末耑區域能量管理(terminal area energy management, TAEM)段中存在的多約束問題,提齣瞭一種 TAEM段約束控製策略。通過俯仰角速率控製 TAEM內迴路,提高瞭控製繫統的穩定性;設計瞭迎角和過載約束控製迴路,在此基礎上,採用動態約束的思想,實時進行約束控製迴路的切換,保證瞭飛行的安全;併分彆在常規控製策略和約束控製策略2種情況下進行瞭倣真驗證。倣真結果證明:採用約束控製策略可以保證RLV迎角和過載不超齣限製,可以保證最終的安全著陸。

For multi-constrained problem of reusable launch vehicle (RLV) in terminal area energy management (TAEM), this paper presents a TAEM constrained control strategy. In order to improve the stability of the control system, pitch rate control is used in the TAEM inner loop. Then, design the angle of attack and overload constrained control loop. On this basis, the control system including dynamic constrain make the system safety by switching the control command. Finally, simulations are processed using normal and constrained control strategy. The simulation results show that: the angle of attack and overload does not exceed the limit using the constrained control strategy, and ensure the safe landing.
