Robust H∞ control for uncertain two-dimensional discrete systems described by the General Model via output feedback controllers

This paper considers the problem of robust H-infinity control for uncertain 2-D discrete systems in the General Model via output feedback controllers. The parameter uncertainty is assumed to be norm-bounded. The purpose is the design of output feedback controllers Such that the closed-loop system is stable while satisfying a prescribed H-infinity performance level. In terms of a linear matrix inequality, a Sufficient condition for the solvability of the problem is obtained, and ail explicit expression of desired output feedback controllers is given. An example is provided to demonstrate the application of the proposed method.
