摘要
根据多输入－多输出控制系统理论，对飞行器耦合的气动伺服弹性系统进行了稳定裕度估算．耦合是在飞行器的横滚与偏航之间产生的．以闭环系统回差矩阵的奇异值理论作为估算方法的基础，应用鲁棒稳定性的充分条件，以某飞行器为例进行估算。
According to the multiinput multioutput (MIMO) system control theory,stability margin of the coupled aeroservoelastic vehicle system was estimated.Couple exists between vehicle's roll and yaw freedoms.Based on the singular value theory about the close loop system's return difference matrix (RDM),and by using the sufficient condition of robust stability,the above estimation method was implemented to get the scope of the resistence of the system disturbence and the maintenance of stability to a vehicle under the given flight velocity.
