飞行航迹解耦控制器设计

Flight Path Decoupling Controller

许多经典的飞行控制系统中,基本飞行控制器纵向和横侧向解耦,可以通过控制飞机的姿态达到跟随参考飞行航迹的目的。对于采用该系统的飞机,当执行航迹跟随任务时,需要设计一种新的解耦控制算法,该算法根据最优参考航迹,将飞机航迹控制指令转化为飞行控制系统所需要的解耦姿态控制指令。给出了由该算法构成的解耦控制器结构,并将其与飞行航迹控制器以及基本姿态控制器结合,共同完成航迹跟随任务。最后通过仿真实验,验证了算法的有效性。

In most of classical flight control systems, the fundamental flight controller was vertical and horizontal decoupled, and it could track the reference flight path through the attitude controlling. For the aircrafts which used the fight control system of this type, a flight path decoupling controller needed to be designed to translate the flight path angle control commands into the attitude angle control commands. To track the optimal reference fight path accurately, a decoupling algorithm had been designed and the controller composed by the algorithm has been given. At last, a simulation experiment had been done, so the effective of the algorithm can be proved.
