基于LQG/LTR的舰载飞机纵向自动着舰控制系统设计

摘要

LQG/LTR methodology is modern state space technique to design the optimization dynamic controller, which has good robustness and decoupling 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 indicate that the control system exactly tracks the longitudinal-directional commands, and it has a good robustness, satisfies the design requirements.%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.
