Metadata-Based Sensor-Displacement Compensation for Networked Water-Temperature Control Systems

Networked water-temperature feedback control sys-tems require the remote temperature measurement at the target position to be controlled. However, a temperature sensor could be displaced during its installation or under operation, which could, in turn, affect the system stability and performance. This study proposes a sensor-displacement compensation method based on an adaptive disturbance observer and adaptive spatiotempo-ral Smith predictor using sensor metadata for a networked water-temperature control system. Simulations confirm that the proposed method outperforms the baseline method, based on the disturbance observer and Smith predictor, in terms of the tracking performance.
