On the sensitivity of the H-infinity norm of interconnected systems with time-delays KU Leuven
We consider delay differential algebraic equations (DDAEs) to model interconnected systems with time-delays. The DDAE framework does not require any elimination techniques and can directly deal with any interconnection of systems and controllers with time-delays. In this framework, we analyze the properties of the H-infinity norm of interconnected systems with time-delays. We show that the standard H-infinity norm may be sensitive to arbitrarily ...
