Abstract :
The problem of the robust H∞ non-fragile controller design for a class of nonlinear neutral systems with uncertainties is studied. Both nonlinear neutral systems and the controller are assumed to have the uncertainties. Suppose that the uncertainties are norm-bounded and the states of the nonlinear neutral systems are all available. Based on the Lyapunov functions, the sufficient condition is established to make the closed-loop nonlinear neutral systems asymptotically stable, as well as satisfying H∞ control properties to achieve disturbance attenuation. The sufficient condition is expressed with linear matrix inequalities which is easy to be solved, and robust non-fragile H∞ controller can be also obtained by solving the linear matrix inequality.
