DR-model-based estimation algorithm for NCS

Abstract

A novel estimation scheme based on dead reckoning (DR) model for networked control system (NCS) is proposed in this paper. Both the detailed DR estimation algorithm and the stability analysis of the system are given. By using DR estimation of the state, the effect of communication delays is overcome. This makes a controller designed without considering delays still applicable in NCS. Moreover, the scheme can effectively solve the problem of data packet loss or timeout.
