巡航导弹地形跟踪的预见控制器设计

一种新的地形跟踪控制方法，即利用已知未来地形信号的预见控制算法设计巡航导弹地形跟踪控制器。针对巡航导弹这个复杂的高阶非最小相位系统，设计前馈与反馈控制器，反愤控制器保证了系统的稳定性与鲁棒性，而前馈控制器则使系统实现精确跟踪。采用上述方案设计的地形跟踪系统具有良好的跟踪特性，对各种千扰和噪声及系统的未建模特性均具有很好的抑制。

Design of Preview Controller for Terrain Following System of Cruise Missile

A new method of terrain following control, the designing for terrain, following system of cruise missile with preview control algorithm, is presented. The feedforward con troller and feedback controller are used to deal with the complicated high-order nonminimum phase system of cruise missile. The feedback controllers assure the stability and robustness of the system, while a perfect following can be achieved by using the feedforward controller. The terrain following system with such a scheme hes good performances and can restrain the vari ous disturbs, noise and the nonmodelized characteristics of the system.
