摘　　要：直升机具有独特的优点,可长时间空中悬停,有良好的低速和超低空飞行特性,可前飞、后飞、左右飞行,机动灵活,对机场依赖小,在发动机停车后能依靠旋翼系统自转下滑安全着陆,因此在军用民用领域得到极其广泛的应用。但是直升机有着更加复杂的气动特性,有着稳定性差,操纵困难等缺点。为了改善直升机性能的不足,直升机上一般安装飞行控制系统(自动驾驶仪、控制增稳系统)以保证其空中姿态稳定。The helicopter has unique advantages, it can hovering in the air for a long time, with low speed and super low altitude flight characteristics,it can fly afterand before flexible, small dependence on the airport, it can rely on the rotor wing system autorotation safely without the engine works, so it is used widely in military and civilianfield. But helicopters have more complex aerodynamic characteristics, the defects are poor stability, difficult to manipulate. In order to improve the performance of a helicopter, flight control system is usually installed on the helicopter （autopilot, control augmentation system） to ensure the air attitude stability.
