Networked Control Systems (NCS) are distributed control systems where the sensor signals to the controllers and the control data to the actuators are enclosed in messages and sent over a communication network. On the one hand, the design of an NCS requires ensuring the stability of the control system and achieving system response that is as close as possible to that of an ideal system which demands network resources. On the other hand, these resources are limited and have to be allocated efficiently to accommodate for future system extensions as well as applications other than control purpose. Furthermore the NCS design parameters for the control system messages and the message transmission over the network are interdependent. In this thesis, we propose “Integrated NCS Design (INtERCEDE: Integrated NEtwoRked Control systEm DEsign)” a novel algorithmic approach for the design of NCS which ensures the stability of the control system, brings system response to that of an ideal system v as close as desired and conserves network bandwidth at the same time. The core of INtERCEDE is a bargaining game approach which iteratively calculates the message parameters and network service parameters. Our experimental results demonstrate the operation of INtERCEDE and how it computes the optimal design parameters for the example NCS.

INtERCEDE: An algorithmic approach to networked control system design

MESSAGE SCHEDULING ALGORITHMS FOR NETWORKED CONTROL SYSTEMS WITH TIME SLOTTED COMMUNICATION PROTOCOLS
Senol, Sinan; Leblebicioğlu, Mehmet Kemal; Schmidt, Ece Gueran (2008-04-22)
Feedback control systems, of which control loops are closed over a real-time communication network, are called Networked Control Systems (NCSs). In this study the message scheduling problem for NCSs with time slotted communication protocols is tackled First, an algorithmic approach is presented to check the necessary and sufficient conditions for a given message schedule such that the real-time requirements of the system are satisfied Second, starting from an initial schedule, Simulated Annealing is used to...
Immune system based distributed node and rate selection in wireless sensor networks
Atakan, Baris; Akan, Ozguer B. (2006-12-13)
Wireless sensor networks (WSNs) are event-based systems that rely on the collective effort of dense deployed sensor nodes. Due to the dense deployment, since sensor observations are spatially correlated with respect to spatial location of sensor nodes, it may not be necessary for every sensor node to transmit its data. Therefore, due to the resource constraints of sensor nodes it is needed to select the minimum number of sensor nodes to transmit the data to the sink. Furthermore, to achieve the application-...
<bold>FlexRay Simulator Development For Networked Control System</bold>
Senoll, Sinan; Leblebicioğlu, Mehmet Kemal; Schmidt, Ece Gueran (2007-06-13)
Feedback control systems, of which control loops are closed over a real-time communication network, are called Networked Control Systems (NCSs). Among major problems in Networked Control Systems (NCS) area is providing Quality of Service (QoS) for the underlying communication network. The stability of the NCS strictly depends on the service received from the communication network. The protocol dynamics were not investigated in most of the previous work for the analysis of the performance of the NCS. In this...
Immune system-based energy efficient and reliable communication in wireless sensor networks

Due to the dense deployment, since sensor observations are spatially correlated with respect to location of sensor nodes, it may not be necessary for every sensor node to transmit its data.
