【Abstract】 In this paper, the problem of robust H_∞ control for a class of uncertain nonlinear system has been investigated. Uncertainty is considered to be parametric and is caused by unknown or time varying model parameters. A corresponding controller is designed for the problem under discussions via the state feedback linearization and a group of LMIs. Both theory analysis and simulation show that the closed loop systems not only keep their states bounded but also satisfy the prescribed L₂-gain.更多还原
