Abstract
En 中文
Sufficient conditions are proposed for the existence of reduced-order (fixed-order) controllers solving the standard nonlinear H-infinity output feedback control problem. State-space formulas for such reduced-order H-infinity controllers are also derived in terms of the solutions of two Hamilton-Jacobi inequalities. The development uses only elementary concepts of dissipativity and differential game, thus the proofs given are simple and clear. (C) 2001 Elsevier Science Ltd. All rights reserved.
