### Unstable and nonproper weights in H-infinity control

Gjerrit Meinsma
Abstract
In this note an ${\cal H}_\infty$ control problem is examined where the controller can and need only stabilize a part of the generalized closed loop due to unstable weights. The procedure is a trivial extension of known results and is computationally the easiest method available.

Keywords: ${\cal H}_\infty$ control theory, stable fractions, Riccati equations.
