Abstract

Closed control loops in communication networks are becoming more and more common as network hardware becomes cheaper and use of the Internet expands. Feedback control systems in which control loops are closed through a real-time network are called NCSs. In an NCS, network-induced delays of variable length occur during data exchange between devices (sensor, controller, actuator) connected to the network. This can degrade the performance of the control system and can even destabilize it [1–11]. It is important to make these delays bounded and as small as possible. On the other hand, it is also necessary to design a controller that guarantees the stability of an NCS for delays less than the maximum allowable delay bound (MADB) [12], which is also called the maximum allowable transfer interval (MATI) [5, 6].
