航空发动机H∞状态反馈控制的鲁棒稳定界
Stability Robustness Bounds for H∞ State Feedback Control of Aeroengine
-
摘要: 对于航空发动机结构参数不确定性系统,引用文献[1]的代数Riccati不等式负定裕度的概念,给出了按基准模型设计H∞状态反馈控制器时确定鲁棒稳定界的方法及其扫描搜索算法。Abstract: The uncertainty system with the structured parameter of aeroengine was investigated,according to T.Shen's conception of the negative margin of algebraic Riccati inequality.The criterions of defining stability robustness bounds for designing the H∞ state feedback controller were provided,based on the nominal model,and its scan-searching algorithm was given.
