Linear H∞-controller design for fuzzy descriptor system based on the dynamic output feedback

The problem of H
∞
-control based on the dynamic output feedback for fuzzy descriptor system was studied. With a equivalent system constructed, the analysis of H
∞
-control for fuzzy descriptor system is converted to the analysis of H
∞
-control for common descriptor system. When the premise variables is unmeasurable, A new method for linear H
∞
-controller design of fuzzy descriptor system is given which avoid analyzing the subsystems of fuzzy descriptor system.
