μ方法在挠性航天器鲁棒控制设计中的应用

Abstract

本文通过对带有挠性附件的一类航天器的鲁棒控制器之设计说明μ方法在不确定挠性航天器姿态控制中的应用。该方法不仅能有效地处理外部干扰以及未建模动态，而且还能直接讨论模型参数的变化，具有较大的应用潜力。但μ最优控制器倾向于激发系统未建模动态，在实际应用中必须特别注意

In this paper, a robust controller For a spacecraFt with Flexible appendage is presented with the aim to exponent the application of μ -synthesis approach in the control of uncertain Flexible spacecraFt.The approach can not only deal with external disturbance and unmodelled dynamics eFFiciently, but can also deal with parameter variations directly.But the μ -optimal controller tends to excite the unmodelled dynamics.Attention must be paid to this phenomenon.
