Abstract :
This paper addresses the problem of non-fragile H∞ controller design for nonlinear systems. The controller to be designed is assumed to have additive gain variations. Design methods for dynamic output (measurement) feedback are presented in terms of positive definite solutions to a pair of coupled Hamilton-Jacobi inequalities. The resulting design is such that the closed-loop system, is robustly stable and has an L2 gain bound with respect to the additive controller gain variations.
