摘要:
 摘要:以高超声速飞行器为背景,针对气动特性与机体弹性形变引起的机体前端的偏转角之间的相互关系,建立高超声速飞行器的一种新型的气动弹性模型。采用活塞理论分析机体受气动力时的弹性形变,通过引入诱发攻角,建立了面向控制的包含气动弹性的高超声速飞行器的非线性模型。通过数值仿真验证了引入诱发攻角的必要性,最后设计了姿态稳定鲁棒控制器,通过非线性仿真结果间接验证了模型的有效性和正确性。提出的描述高超声速飞行器气动弹性问题的思路和方法,同样适用于其它构型的飞行器,并且此模型的变量维数远小于其它同类模型,降低了后续工作中控制器设计的难度。
Abstract:
 Abstract:Based on hypersonic vehicle,considering the influence between aeroelastic characteristic and a deflection angle in the front of the vehicle generated by vehicle elastic deformation,a new aeroelastic model of hypersonic vehicle was built. Elastic deformation made by aerodynamic force acting on vehicle by piston theory was analyzed,and a nonlinear model was built including aeroelasticity hypersonic vehicle. The numerical simulations prove it is necessary to introduce induced angle of attack,then attitude stabilization robust controller was designed,and the closed-loop system simulation result of nonlinear model verifies the validity and correctness of the model indirectly. The method to describe hypersonic vehicle aerodynamic elastic problem was proposed,which is applicable to other vehicles with different configuration,and the dimension of this model is far smaller than others,which makes it easier to design the controller.
