This study delves into the distributed estimation of states in discrete-time switching systems, while considering external disturbances and measurement noises. We present a distributed interval observer to achieve the above goals in this study. The positivity requirement for the interval observer is eliminated by introducing an internal positive representation technique, and the common Lyapunov function is applied to justify the feasibility of the proposed observer. Finally, simulation of the theorem with a numerical example.

摘要

This study delves into the distributed estimation of states in discrete-time switching systems, while considering external disturbances and measurement noises. We present a distributed interval observer to achieve the above goals in this study. The positivity requirement for the interval observer is eliminated by introducing an internal positive representation technique, and the common Lyapunov function is applied to justify the feasibility of the proposed observer. Finally, simulation of the theorem with a numerical example.
