摘要
运用中心流形—范式综合方法 ,从理论上讨论了高维磁悬浮柔性转子控制系统二次状态反馈鲁棒稳定性问题。提出了此类高维控制系统渐近稳定的条件和二次状态反馈稳定定理 ,给出了此高维系统二次反馈控制律的构造方法 ;最后 。
By theoretical analysis, state feedback robust stability is discussed for a 5D magnetic levitation flex-rotor control system, by the integrated method of center manifold and normal form. The condition is g iven under which the simplified vector field is asymptotically stable; and suffi cient conditions for the existence of stabilizing controls are also given. Doubl e state feedback theorems are derived for the multidimensional system. Finally, selection method of feedback control law is obtained, and a theorem is proved re garding the robustness of the above control law.
