摘　　要：针对面对称高超声速飞行器的飞行姿态控制问题,分析了姿态动力学系统的复杂非线性和各通道间的强耦合特性,建立了高超声速飞行器在离散域上的状态空间模型,得到高超声速飞行器受控飞行下的姿态演化规律;在每个控制节拍中,预测、估计飞行器未来的状态变化及系统误差,根据飞行器姿态受控变化的动力学反演姿态控制指令;针对飞行器模型误差和内、外部扰动所导致的控制偏差设计控制补偿,提出了一种基于模型预测和动力学反演,满足时间约束的高超声速飞行器姿态高精度控制方法。考虑工程实际应用中存在的建模误差,对该方法进行了仿真验证。仿真结果表明该方法具有较好的控制精度和响应速度,对于模型参数的不确定和各种扰动具有良好的鲁棒性。Aiming at the problem of flight attitude control of symmetric hypersonic vehicles,the complex nonlinearity of the attitude dynamics system and the strong coupling between each channel are analyzed,and the state-space model of the hypersonic vehicle in the discrete domain is established to obtain the attitude evolution law of the hypersonic vehicle under controlled flight.In each control beat,the future state change and system error of the vehicle are predicted and estimated.The ttitude control command is inverted according to the dynamics of the controlled change of vehicle attitude.The control compensation is designed for the control deviation caused by internal and external disturbances.A high precision attitude control method is proposed for hypersonic vehicle based on model prediction and dynamics inversion,which can meet time constraints.Considering the modeling errors in practical engineering applications,the proposed method has been simulated and verified.The simulation results show that the method has good control accuracy and response speed,and has good robustness to the uncertainty of model parameters and various disturbances.
