本計畫主要研究一般性nonaffine非線性取樣系統H/sup ∞/控制器之參數化問題。吾人推導一族H/sup ∞/控制器之狀態空間表示式。此族H/sup ∞/控制器具有離散時間系統串接一廣義持住函數之架構。 This project studies the H/sup ∞/ control problem for more general nonaffine nonlinear systems with sampled measurements. Sufficient conditions for existence of a family of H/sup ∞/ controllers built from sampled measurements are presented. State-space formulas for such a family of H/sup ∞/ controllers are also derived. It is proven that the family of controllers thus obtained has the structure of a discrete-time system followed by a generalized hold function. The results extend recent achievements in the literature.
