aircraft control system meaning in English

飞机操纵系统

Quantitative feedback theory ( qft ) is developed much quickly in these years . there are many advantages in using it to design aircraft control systems
定量反馈理论是近年发展比较快的理论，利用它设计飞控系统具有很大的优越性。
The aircraft ' s longitudinal motion short period poles and long period zeros in right plan e may make the aircraft control system be not got by only using qft . so pole and zero assignment by state feedback is needed to change this circumstances and then qft is used to get the control system . simulink results are given to prove at the system meets the requirements .
飞机纵向运动方程的短周期和长周期的右半平面可能存在零极点对问题，这对飞机控制造成不利影响，直接利用定量反馈理论不能满足要求。本次论文首先进行短周期状态反馈极点配置，然后利用定量反馈来解决这个问题。通过仿真分析得到满意的结果。
