Optimal sensor placement and online spatiotemporal modeling for parabolic distributed parameter system under sparse sensing
Published on 2026-05-28 by @OXFORD
Abstract: AbstractRestrictions on the number and placement of sensors are common in the modeling of parabolic distributed parameter systems (DPSs). Since the information from measurements is incomplete, developing an accurate approximation model and capturing their dynamic behavior for time-varying DPSs under sparse sensing is a challenge. In this paper, a novel online spatiotemporal modeling framework including data completion and optimal sensor placement is developed. Firstly, in the offline initializat[...]
