Abstract:
|
The successful operation of Networked Control Sys-
tems (NCS) requires employing appropriate approaches
for dealing with network induced time delays, i.e. time
intervals elapsed from consecutive sampling and actua-
tion operations. Effective approaches often require to im-
pose periodic execution for the sampling and/or actuation
operations, enforcing synchronized constant time delays.
And considering that sampling and actuation is performed
in different nodes, global time between nodes achieved by
clock synchronization is the standard assumption or strat-
egy that enables such synchronized operations. This pa-
per presents a technique that permits to implement these
synchronized operations in NCS in the absence of global
time. Experimental results corroborate the effectiveness
of the presented approach. |
