Active control on the vibration of flexible satellites - Variable structure control method and experiment

摘要

The flexible satellites with large solar panels require strong robustness of attitude control systems, so that good dynamic properties and high precision of attitude orientation and adjustment can be maintained even under the action of various uncertainties. As solar panels have been placed on some new type of our satellites, it is necessary to study the control schemes and the corresponding experiments from the viewpoint of engineering. Many practical factors having been considered, a variable structure control (VSC) scheme is proposed here to actively suppress the vibration of flexible satellites and the scheme is realized on an experimental setup. Thus, the first vibration active control experiment for flexible structures in our country is successfully done. Having analyzed many open reports, we know that it is the first time to apply the VSC theory to such experiments in the world.
