The performance of a class of Model-Based Networked Control System (MB-
NCS) is considered in this paper. A MB-NCS uses an explicit model of the
plant to reduce the network bandwidth requirements. In particular, an Out-
put Feedback MB-NCS is studied. After reviewing the stability results for this
system and some lifting techniques basics, two performance measures related
to the traditional H2 performance measure for LTI systems are computed.
The first H2 like performance measurement is called the Extended H2 norm
of the system and is based on the norm of the impulse response of the MB-
NCS at time zero. The second performance measure is called the Generalized
H2 norm and it basically replaces the traditional trace norm by the Hilbert-
Schmidt norm that is more appropriate for infinite dimensional operators.
