弹性飞行器时域稳定鲁棒性分析

TIME-DOMAIN STABILITY ROBUSTNESS ANALYSIS OF ELASTIC VEHICLES

从时域内对存在模型误差的弹性飞行器控制系统进行了稳定鲁棒性研究。给出了稳定鲁棒性设计准则及稳定鲁棒性测度的概念,提出了弹性飞行器控制系统稳定鲁棒性最优综合及振动抑制的方法。

The stability robustness for uncertain system models of elastic vehicles is studied in time-domain. A criterion for measuring stability robustness of system is obtained by analysing the stability robustness of output feedback regulator control system of elas-tic vehicle. A concept on measure of stability robustness to show an inherent quality of system is also defined.Finally, optimal stability robustness synthesis of system is presented by dislocating the actuator/sensor position and adjusting feedback law.A method for elas-tic vibration suppression is given too.
