Non-Fragile Robust H∞ control for a class of Uncertain Singular systems with Multiple time delays:an LMI approach

摘要：

To a class of complex uncertain singular systems with multiple time delays in state and control input,This paper con-siders the problem of non-fragile H∞, controller design method .First,based on the stability criterion and linear matrix inequalities(LMIs), a sufficient condition of the existence of the non-fragile H∞, controller is established .Then the problem of control is solved via a robust controller with gain additive and multiplicative perturbations, the designed conn oiler guarantees that the closed-loop system is regular,impulse free and asymptotically stable for all admissible uncertainties , more over, also satisfies H∞performance index, which has better adaptability against variety of the environment parameter. A numerical example demon-strates that the systems are robust to both the uncertainty of parameters and perturbations of controller gain.
