Sufficient conditions for the solvability of the considered problem are represented in terms of two Hamilton-Jacobi inequalities with n independent variables. Based on these conditions, a state space characterization of a robust output feedback H ∞ controller solving the considered problem is provided.H∞ controlnonlinear systemsrobust performancestructured uncertaintydiscrete-time systems
