摘　　要：根据高超声速飞行器的姿态动力学方程,给出一个可面向姿态角速度镇定的非线性设计模型。针对一类非线性系统,提出一种基于扩张状态观测器(ESO)的鲁棒动态逆设计方法,并将其应用于高超声速飞行器姿态角速度的渐近镇定中。仿真结果表明,相比传统的动态逆控制方案,本文所提出的控制方案可保证飞行器姿态角速度得到快速镇定,并且具备针对模型不确定和结构干扰力矩的强鲁棒性能。According to the attitude dynamics equations of hypersonic vehicle, a nonlinear model oriented to attitude angular speed stabilization is established. Regarding a class of nonlinear system, a robust dynamic inversion control （DIC） approach is proposed, which is based on extended state observer （ ESO ） , and then it is utilized to stabilize the attitude angular speed of hypersonic vehicle. The simulation results show that, the proposed control scheme can ensure the attitude angular speed of chosen vehicle is stabilized more rapidly by comparing with the traditional DIC scheme and it possesses more robust property with respect to modeling uncertainties and structural disturbance torques.
