摘　　要：LQG/LTR方法是一种设计优化动态控制器的现代状态空间技术。此方法具有良好的鲁棒性能和解耦特性。运用LQG/LTR方法设计了舰载飞机自动着舰控制器,并在考虑甲板运动和气流扰动的情况下,对纵向自动着舰控制系统进行了仿真设计与分析。系统仿真结果表明,控制系统实现了纵向指令的精确跟踪,具有良好的鲁棒性,满足舰载飞机纵向着舰控制的要求。LQG/LTR methodology is modem state space technique to design the optimization dynamic controller, which has good robustness and de.coupling characteristics. The automatic landing control system laws were designed by LQG/LTR design methodology, design takes into consideration random deck motions and air turbulence, designs and analysises the automatic landing control system for longitudinal control laws. The simulation results in- dicate that the control system exactly tracks the longitudinal-directional commands, and it has a good robustness, satisfies the design requirements.
