Johansson, KTH, Sweden<br /> &lt;/P&gt;<br /> <br /> &lt;B&gt;Abstract&lt;/B&gt;<br /> &lt;BR&gt;<br /> There is a growing deployment of wireless networks in industrial<br /> control systems. Lower installation costs and easier system<br /> reconfigurations for wireless devices can have a major influence on<br /> the future application of distributed control and monitoring. There is<br /> however a lack of theory for understanding if and how the allocation<br /> of communication resources should be integrated with the control<br /> application. In this talk, we will discuss how the access scheme for<br /> the wireless medium can influence the closed-loop performance of the<br /> networked control system. It will be argued that the underlying<br /> scheduling-control problem has a non-classical information<br /> structure. Appropriate models for medium access control protocols will<br /> be introduced. It will be shown how these protocols can be tuned for<br /> various wireless control applications. We will also see that by making<br /> asynchronous transmissions based on decisions taken locally at the<br /> sensor and actuator nodes, it is possible improve the design and to<br /> limit the use of the communication resources. The talk will be<br /> illustrated by several examples from ongoing projects with Swedish<br /> industry. The presentation is based on joint work with collaborators<br /> at KTH.</div>
