Two structures for resource constrained control systems with output feedback

In this work a model-based output control scheme for resource constrained control systems using output feedback is proposed. In this context resource constrained means limited energy and limited computational resources mainly in the sensor. A heuristic adaptation law schedules the transmission intervals in order to cope with these constraints. Two different structures are presented: An observer based approach, which is an extension of [1] and a novel approach which uses a system model of reduced order. An LMI-based stability criterion is given for both approaches. A simulation study shows the effectiveness of adaptation in both cases. Advantages of the reduced model approach concerning resource constraints are discussed.
