Abstract :
State-space formulas are derived for a family of controllers solving the standard nonlinear H∞ output feedback control problem. The formulas given are simple and explicitly expressed in terms of the solutions of two Hamilton-Jacobi inequalities in n independent variables. It is also shown that these controllers are obtained by interconnecting the “central controller” with a free, asymptotically stable system having L2-gain⩽γ. The development uses the concepts of dissipativity and differential game, thus the proofs are simple and clear
