摘要
本文利用人机半物理仿真法，研究了大气紊流对飞机突防飞行的解耦控制特性、驾驶员的操纵性及乘坐品质的影响，检验了非线性解耦控制系统对驾驶员实时操纵指令的跟踪特性。结果表明：解耦控制律能够在大气紊流扰动下解除飞机纵横向运动的非线性交叉耦合，＿有良好的解耦操纵性能和乘坐品质，减轻了驾驶员的操纵负担，从而提高了低空突防飞行的安全性。
The effect of turbulent disturbance on the behavior of decoupling control in case of an aircraft penetrating at low level by using TF/TA technologies and control and its riding quality of the pilot are studied by pilot-vehicle semi-physical simulation technique. At the same time, the tracking behavior of nonlinear decoupling system on the real-time control command of the pilot is verified,too. The simulation results show that some nonlinear cross couple between longitudinal and lateral movements of the aircraft can be eliminated by the decoupling control law, and it offers better decoupling control and riding quality of the pilot. The work load of the pilot could be reduced greatly, and the result of research theory is verified, too.
