Abstract :
Sufficient conditions are proposed for the existence of reduced-order (fixed-order) controllers solving the standard nonlinear H ∞ output feedback control problem. State-space formulas for such reduced-order H∞ controllers are also derived in terms of the solutions of two Hamilton-Jacobi inequalities. The development uses only elementary concepts of dissipativity and differential games, thus the proofs given are simple and clear
