Parameter Estimation over Wired Networks with Time-Delay and Packet Collision

摘要

In this paper, we address a parameters estimation problem of a dynamic system using an Output Error model, in which the output signal is transmitted through wired networks. We consider that the wired network may cause unknown delays and collision packet in data. We use the Akaike information criterion to estimate the time delay caused by wired network. Furthermore, due to the packet loss caused by wired network, we use Expectation Maximization algorithm to estimate the dynamic system parameters. Finally, we test the proposed algorithm effectiveness with numerical examples and a sensitivity analysis.
