  This paper analyzes the stability of the control system of an Autonomous
Guided Vehicle (AGV) using a central controller. The control commands are
transmitted to an AGV over a Rayleigh fading channel causing potential packet
drops. This paper analyzes the mutual dependencies of control system and mobile
communication system. Among the important parameters considered are the
sampling time of the discrete control system, the maximum tolerable outages for
the control system, the AGV velocity, the number of users, as well as mobile
communication channel conditions. It is shown that increasing the velocity of
an AGV leads to a lower risk of instability due to the higher time-variance of
the mobile channel. While this still is a 'sandbox' example, it shows the
potential for a manifold co-optimization of control systems operated over
imperfect mobile communication channels.
