| 摘 要： | 针对飞行控制系统设计中存在的建模误差以及实际飞行中外界干扰的影响,采用LQG/LTR鲁棒控制方法完成了某型攻击机横航向控制设计,解决了在飞机模型不确定性、随机干扰下控制系统可能出现的不稳定和控制精度不够的问题。系统仿真结果表明,控制系统实现了横航向指令的精确跟踪,不但具有良好的鲁棒性,而且调节性能良好,满足飞机横航向控制的要求。

| Abstract: | A robust lateral-directional flight control system for an attack aircraft was developed using LQG/LTR to address control system instability and insufficieot control precision,as caused by aircraft model uncertainty and random disturbance.A system simulation shows that the control system exactly tracks the lateral-directional commands,and it not only has a good robustness,but also provides good control accuracy to satisfy the design requirements. |
