Abstract

Considers the observer design problem for a continuous-time system when the output is event-based. For the case of linear time invariant system with an output in finite alphabet the authors develop a hybrid observer which is represented as a combination of continuous-time dynamics and nonuniformly sampled discrete-time system. The design idea uses generalization of the sliding mode concept for discrete-time systems in the form of dead-beat controllers and observers. It is shown that even for the linear case the observation problem is not independent from the control which can be used to regulate the observation process
