基于分数阶微分理论和Lyapunov函数的构建,对一类含不确定项的退化分数阶系统进行鲁棒镇定研究.首先利用“descriptor form”方法构造了一类新分数阶系统,然后利用状态反馈控制得到系统鲁棒镇定条件,最后结论以LMI方法给出,易于求解反馈增益矩阵. |

Abstract: |
Based on fractional differential theory and Lyapunov function,this paper researches robust stabilization for a class of singular fractional systems with uncertainties.This paper firslty constructs new fractional system by “descriptor form” method.Using state feedback control,the condition of robust stabilization is established,and the results given by LMI that are easy to resolve the gain matrix in the system. |
Key words: singular fractional order robust stabilization uncertainties |
