A Network-Friendly Implementation Architecture for Observer-Based Intermittent Controllers

Abstract This note studies implementation issues arising in observer-based controllers acting under intermittent information exchange between their sensor-and actuator-side parts. Existing implementation schemes assume that a copy of the control signal generator runs on the sensor side. This might render the controller sensitive to some network-induced problems, like packet losses. We propose an alternative architecture, in which the sensor-side part does not need to know the actual control signal. As a result, stabilizing and optimal controllers can be successfully implemented over unreliable networks.
