摘　　要：对飞机纵向地形跟随控制系统控制律的设计问题进行了研究。为了消除干扰,提高跟踪效果,首先以飞机的纵向运动状态为研究对象,建立了相应的自动地形跟随控制系统结构模型,再应用模糊控制的方法分别通过控制航迹角和控制法向加速度两种方案设计了飞机纵向地形跟随系统的控制律,同时给出了仿真验证的模型,然后对模型各个输出的特性以及地形跟随的效果进行了仿真验证,仿真结果表明,设计的控制系统得到了良好的地形跟随效果,最后以控制航迹角的系统响应曲线为例,通过与传统的PID控制效果进行对比,说明经过模糊控制的系统具有良好的抗干扰性。The control law of automatic terrain following control system of modem aircraft is designed. First, the longitudinal model of aircraft is mainly studied by using the adaptive angle method. Then, the fuzzy control law of automatic terrain following system is designed separately by controlling the flight path angle and controlling the normal acceleration. Moreover, the simulation models are represented. The simulation results indicate that the control system designed is feasible and valid. In the end, the output of the path angle is taken for an example to illustrate that, compared with the traditional PID control system, the fuzzy control system is normally more stable.
