| 摘 要： | 针对高超声速飞行器姿态控制问题,设计了具有鲁棒特性的自动驾驶仪;针对带有耦合特性的面对称外形高超声速飞行器的动力学模型,在存在气动参数摄动的情形下,基于数值有界不确定性描述形式,利用鲁棒控制理论和线性矩阵不等式(LMl)求解方法,设计了三通道鲁棒的自动驾驶仪控制器;最后仿真结果表明,所设计的三通道自动驾驶仪使得高超声速飞行器获得理想的动态性能和稳态品质,并对气动参数和通道间的耦合不确定性具有较强的鲁棒性.

| Abstract: | According to the attitude control problem of the hypersonic vehicle,the autopilot with robustness is designed.According to the dynamic model of the hypersonic vehicle with plane-symmetry having coupling characteristic and changes of the aerodynamic parameters,the controllers of the three-channel autopilot with robustness are designed using the robust control theory and the LMI solving method based on the element bounded uncertainty describing form.Finally,the simulation results show that the hypersonic vehi... |
