Zhu Xiaoping; Zhou Zhou(Nanjing University of Aeronautics and Astronautics, Nanjing, China, 210016)Chen Shilu(Northwestern Polytechnical University, Hi'an, China, 710072)  
Variable structure control (VSC) applied to atmospheric disturbance sup-pression is presented. The conditions are stipulated: the sliding mode existenee condi-tion, and invanance condition of atmospheric disturbanee in the variable structuresystem (VSS). A method of eigenstructure assignment technique for switching surfaeedesign is proposed. Based on different atmospheric disturbanee characteristics, such asrandom turbulence, discrete gust and wind shear, two kinds of control laws are derived that possess strong robustness. An example shows that this control approach isfeasible and effective.
