Keynote at EBCCSP:
Model-based event-triggered control for networked systems
In the Model-Based approach to the control of Networked Systems (MB-NCS) a nominal approximate model of the plant dynamics is used to estimate the state of the plant during the intervals of time feedback measurements are not available to the controller. It has been common practice in MB-NCS to reduce network usage by primarily using periodic updates. Time varying update intervals can be and have been used. The update intervals may also be decided based on the current conditions and response of the plant as it is the case in Event-Triggered Control (ETC). The MB-NCS framework will first be introduced and results of ETC in MS-NCS will be discussed.

Keynote at EBCCSP:
Data conversion and digital signal processing using event-based, continuous time techniques
Many new and emerging applications require extremely low power dissipation in order to preserve scarce energy resources; such applications include sensor networks and wearable/implantable/ingestible biomedical devices. In such cases, uniform sampling, as used in conventional, clocked circuits, represents undesirable and unnecessary energy waste. We review techniques in which the signal itself dictates when it needs to be sampled and processed, thus causing energy use only when demanded by the information in it. Methods for implementing event-driven A/D converters and DSPs in this context, without using any clock, are reviewed. It is shown that, compared to traditional, clocked techniques, the techniques reviewed here produce circuits that completely avoid aliasing, respond immediately to input changes, result in better error spectral properties, and exhibit dynamic power dissipation that goes down when the input activity decreases. Experimental results from recent test chips, operating at kHz to GHz signal frequencies, fully confirm these properties.
