摘　　要：V尾翼身融合飞机可以看成是一种具有较高的隐身特性的低阻尼系统,特殊的构型使得其系统参数和操纵特性与常规飞机有所区别,采用线性二次型的控制算法设计了其飞行控制律并进行了仿真与评估,搭建了纵向的俯仰角速率控制构型、副翼方向舵交联、横向的滚转阻尼器、航向的增稳器和阻尼器并进行了MATLAB/SIMULINK仿真,最后利用等效系统拟配的方法对"飞机本体+飞控系统"的高阶系统的特性进行了评估,得出了所设计的控制系统在增加纵向系统的阻尼比和横航向系统的阻尼比和自然频率的同时,还会对纵横交感现象起到一定的改善作用。Blended-wing-body(BWB)aircrafts with vee tail is a typical stealth aircraft of unconventional configuration,which is blended-wing-body aircraft equipped with vee tail.But the steering characteristics of the system are more complicated.As the BWB aircraft with vee tail doesn’t meet the requirements of flying qualities and agilities,the flight control system was established.Then by using the Optimal Liner Quadratic with output feedback,the flight control laws were designed and simulated.Low-order equivalent systems in aircraft handing qualities were calculated.Finally,the improvement effects of control augmentation system were studied on.
