Abstract

The paper deals with the state estimation of networked visual servo control systems (NVSCS) using sampled and delayed output measurements. A continuous state observer is proposed which makes possible to estimate the NVSCS state in the case of fixed sampling period and variable and bounded time delay. The stability of the new state observer is studied in detail. The performances of the proposed observer are compared by numerical simulations with those of the Lyapunov–Krasovskii state observer.
