Abstract :
In this paper, we consider a state feedback H∞, control problem for a nonlinear system with gain bounded perturbations. We derive nonlinear matrix inequality (NLMI) conditions which are equivalent to a sufficient condition for the existence of a solution of a nonlinear robust H∞ control problem. Then a set of a certain class of nonlinear robust H∞ controllers is parametrized in the state space using a matrix valued function L(x) of fixed dimension with a norm bound and the positive definite solutions to the NLMIs
