| 摘 要： | 针对大型客机放宽静稳定性后纵向稳定性和操纵品质不足等问题,采用LQG/LTR理论及方法设计了一种纵向控制增稳系统,并通过典型重心位置和飞行阶段的仿真,表明该系统具有比经典控制增稳系统更为理想的增稳效果、鲁棒性、抗干扰能力和操纵品质。

| Abstract: | A control augmentation system has been designed based on the LQG/LTR method for a large jet to heal the degeneration of longitudinal stability and handling qualities of the plane due to static-stability relaxing.The dynamic responses,robustness,turbulence endurance,and handling qualities of this system have been verified through simulant test under different flight conditions and over a wide range of c.g.locations.Testing results show that the RSS airplane could achieve more satisfactory longitudinal stabil... |
