Abstract :
Sufficient conditions are proposed for the existence of reduced-order (fixed-order) controllers solving the H∞ control problem for nonaffine nonlinear systems. State-space formulas for such reduced-order H∞ controllers are also derived in terms of the solutions to two standard Hamilton-Jacobi-Isaacs inequalities
