On the Design of Reduced-Order H-infinity Controllers for Nonaffine Nonlinear Systems

Abstract

本論文提出nonaffine非線性系統之低階H-infinity控制器的充分條件. 此低階H-infinity控制器的狀態空間之實現由標準Hamilton-Jacobi-Isaacs inequalities的解表示之. Sufficient conditions are proposed for the existence of reduced-order (fixed-order) controllers solving the H-infinity control problem for nonaffine nonlinear systems. State-space formulas for such reduced-order H-infinity controllers are also derived in terms of the solutions of two standard Hamilton-Jacobi-Isaacs inequalities.
