无人作战飞机对地攻击火/飞耦合控制器设计

摘要

针对实现无人机对地攻击构建攻击综合火力/飞行控制系统的关键问题,提出设计一种以耦合控制器结构完成现有分离的火控系统和飞控系统的综合.由火控系统解算出无人机对地攻击的攻击区和投弹区并生成参考攻击轨迹,耦合控制器根据参考攻击轨迹,控制无人机进行参考攻击轨迹跟踪.设计耦合控制器综合控制策略,避免了因纵向通道和横侧通道交联带来的控制误差；设计耦合控制单元,完成舵机和副翼的偏转量的解算.仿真结果表明:该耦合控制器能根据目标位置较好的完成控制量解算,控制无人机进行轨迹跟踪,实现对地攻击.%Aiming at the critical problems achieved UAV air to ground attack of constructing integrated fire or flight control system, the coupled controller structure to complete integration based on the separated fire control system and flight control system. Fire control system calculated UAV air to ground attack zone and bomb-dropping zone, and generates reference attack track. According to reference attack track, and the coupled controller contrails UAV followed the track. To avoid errors brought by crosslink between portrait and lateral channel, integrated control tactics are designed. To calculate controlled variable of elevators, rudders and ailerons, coupled controlled units are also designed. Simulation results shows that the coupled controller can calculate controlled variables preferably on the basis of target location, control UAV follows the track and achieve air to ground attack.
