Efficient Linear Sensor Fusion Over Multiple Lossy Channels With Local Observability
Yuchi Wu, Yuzhe Li, Ling Shi · IEEE Control Systems Letters · 2019
In this letter, we consider a computationally efficient sensor fusion scheme for obtaining a remote state estimate of a single linear process based on the data packets from the smart sensors which are transmitted through several independent lossy channels. Local observability at each smart sensor is assumed. We transformed the problem of finding the optimal linear sensor fusion coefficients as a semi-definite programming (SDP), which can be efficiently solved. Simulation results are presented to illustrate the performance of the developed algorithm.
