飞机对大气扰动的变结构控制

VARIABLE STRUCTURE CONTROL OF AIRCRAFT FOR ATMOSPHERIC DISTURBANCE

研究了飞机对大气扰动的变结构控制系统滑动超平面特征空间结构设计方法，针对不同的大气扰动特性（随机紊流、离散突风和风切变等），提出了具有鲁棒特性的变结构控制律。

Research results on variable structrue control applied to atmospheric disturbance suppression are presented.The conditions are stipulated:the sliding mode existence condition,and invariance condition of atmospheric disturbance in variable structrue system(VSS).A method of eigenstructure assignment technique of switching urface is proposed.Based on different atmospheric disturbance characteristics, such as random turbulence, discrete gust and wind shear, two kinds of control laws are derived that possess strong robustness. An example shows that this control is feasible and effective.
