Show more >This work concerns the observer-based control of a remote, Master-Slave system through the Internet network. This communication link introduces variable, asymmetric and unpredictable delays, as well as packet loss. The data-sampling effects are also taken into account, even in the aperiodic case. Whereas the existing strategies require additional buffers, allowing the delay to become constant, the present result uses the information as soon as received. The proposed Lyapunov-Krasovskii functionals and LMI algorithms provide controller and observer gains which ensure the asymptotic stability of the global closed loop. The maximum admissible number of successive packets dropouts is also computed. The last part of the paper provides a simulation, where the Slave is a second-order system.Show less >
