The Non-fragile Robust H∞ controller design with system uncertainty

摘要

This paper presents a non-fragile robust H∞ controller design with system uncertainty.With the additive controller gain variations,the necessary and sufficient conditions for the existence of non-fragile state feedback controller are given and transformed to the LMI problems,which simplifies the solutions to get non-fragile robust H∞ state feedback controllers.The flight control simulation results show the reliability and validity of the method.
