Abstract: |
This paper considers H-infinity control problem for interval descriptor systems. Necessary and sufficient
LMI-based conditions are derived for quadratic-like H-infinity control analysis of interval descriptor systems. Using the
analysis result, two types of feedback controllers are designed so that the closed-loop interval descriptor systems are admissible
with H-infinity-norm less than a prescribed value. To the best of the authors’s knowledge, this is the first paper to
deal with the H-infinity control problem of interval descriptor systems in the literature. |
