建立了“类X-20”高超声速飞行器的动力学模型,针对攻角、侧滑角和滚转角三通道之间的强耦合性,提出了一种同时考虑状态耦合和输入耦合的全通道耦合特征模型,基于此特征模型设计由多输入多输出黄金分割自适应控制律、微分控制律和积分控制律相结合的组合控制器.最后,分别对精确模型和干扰模型进行仿真,验证控制器的跟踪能力及鲁棒性,并与单通道控制器比较,结果表明全通道耦合特征模型控制器在高超声速飞行器姿态控制方面具有明显优越性. A dynamic model of the “X-20” hypersonic vehicle was established. According to the strong coupling between the angles of attack, the sideslip angle and the roll angle of the three-channel, a state-based and an input-coupled Channel coupling feature model, based on this feature model, a combined controller combining multi-input and multi-output golden section adaptive control law, differential control law and integral control law is designed.Finally, the precise model and the interference model are respectively simulated to verify the control The tracking capability and robustness of the proposed model are compared with those of the single-channel controller. The results show that the full-channel coupled model controller has obvious superiority in hypersonic vehicle attitude control.
