研究运载器再入姿态稳定控制问题,亚轨道可重复使用运载器(Suborbital Reusable Launch Vehicle,SRLV)的再入,环境变化剧烈,非线性严重,系统的稳定性受到影响。针对传统控制器在飞行器大空域飞行、系统参数大范围变化时,控制能力欠缺的问题,提出了应用模型参考自适应的控制算法,对系统模型进行自适应控制,设计了SRLV再入返回段的姿态控制器。通过其在Matlab平台上进行仿真,结果表明,改进算法在环境参数剧烈变化和系统具有较强不确定性的情况下,能够对SRLV进行鲁棒、精确的控制,为运载器再入姿态控制提供了参考。
The stability control of reentry vehicles was studied. Reentry of Suborbital Reusable Launch Vehicles (SRLV) was carried out. The environment changed drastically, the nonlinearity was serious and the stability of the system was affected. Aiming at the problem that the traditional controller is lacking of control ability in the large space flight of the aircraft and the system parameters vary widely, a control algorithm based on adaptive model reference is proposed to adaptively control the system model. Gesture Controller. The simulation results show that the proposed algorithm can robustly and accurately control the SRLV under the circumstance of dramatic changes of environmental parameters and strong uncertainty of the system. For reference.
