Remote State Estimation over an Attenuation Channel in Flight Control Systems

Reliability of real-time fight control system is more relevant with the development of wireless communication. However, due to the existence of the attenuation channel in communication and the limit of transmission power, it is difficult to accurately project control performance. In this paper, we choose a block attenuation channel model to derive its state estimation algorithm, find the critical thresholds in sensor scheduling strategies which can achieve optimal estimation performance with the derived algorithm, and compare the effect of different scheduling strategies on estimation performance. Results show that the optimal estimation performance can be achieved by utilizing an even transmission strategy.
