Abstract
First, we review some previous work on networked control systems
(NCSs) and offer some improvements. Then, we summarize the fundamental
issues in NCSs and examine them with different underlying
network-scheduling protocols. We present NCS models with network-induced
delay and analyze their stability using stability regions and a hybrid
systems technique. Following that, we discuss methods to compensate
network-induced delay and present experimental results over a physical
network. Then, we model NCSs with packet dropout and multiple-packet
transmission as asynchronous dynamical systems and analyze their
stability. Finally, we present our conclusions
