摘　　要：考虑高超声速飞行器再入飞行的稳定姿态控制需求,本文围绕气动舵控制能力约束和不确定干扰的问题,利用通道耦合特性开展协调鲁棒自适应控制技术研究.基于副翼舵偏角和升降舵偏角协调的策略提出分层控制设计,实现通道耦合利用以弥补方向舵低舵效引起的操纵不足.针对动力学不确定估计和外界干扰观测的需求,采用模糊逻辑系统以及误差鲁棒积分技术建立平行估计模型,提出利用预测误差的复合估计自适应律.通过Lyapunov方法分析闭环系统稳定性,并保证闭环系统的误差信号一致终值有界.通过仿真测试验证了所提出算法的跟踪性能、学习准确性和鲁棒性.Considering the requirements for stable attitude control during the reentry flight of hypersonic vehicles,this paper focuses on the constraints of aerodynamic rudder control capabilities and the issues of uncertain disturbances,utilizing the channel coupling characteristics to explore coordinated robust adaptive control technology.A hierarchical control design strategy based on the coordination of aileron and elevator deflection angles is proposed,achieving channel coupling utilization to compensate for insufficient control caused by low rudder effectiveness.To address the need for dynamic uncertainty estimation and external disturbance observation,a parallel estimation model is established using fuzzy logic systems and robust error integration techniques,proposing a composite estimation adaptive law based on predictive error.The stability of the closedloop system is analyzed using the Lyapunov method,ensuring that the error signals of the closed-loop system are bounded in the final value.The tracking performance,learning accuracy,and robustness of the proposed algorithm are verified through simulation tests.
