摘　　要：提出了一种非线性PD控制方法,并将其应用在自动地形跟随系统飞行控制律的设计中。对采用常规PI控制与非线性PD控制的飞行控制系统进行了鲁棒性仿真比较以及典型地形跟随误差仿真比较。结果表明,采用非线性PD控制方法设计的控制律具有良好的鲁棒性与跟随性能。A nonlinear PD controller is presented in this paper and is used in the design of the control laws for an automatic terrain following flight control system . The robustness and tracking performance for using the PI control method and the nonlinear PD control method are compared by simulation. The automatic terrain following flight control system designed by the nonlinear PD control method is of stronger robustness and better tracking performance.
