Discussion on: Stabilization of Networked Control System with Time Delays and Data-packet Losses
Résumé
In this paper, we provide experimental results in the application of the results of [4]. Based on the theoretic work in [4], we propose an estimator-based delaycompensation algorithm to stabilize a networked control system (NCS) with network-induced stochastic time delays, data-packet losses, and out-of-order data-packet transmissions. With the p-sampling-period delay upper bound, the NCS can also accommodate up to p – 1 successive packet losses. We also derive sufficient conditions for the stability of the NCS. The feasibility and effectiveness of the theoretic results of [4] is verified experimentally using an NCS test bed incorporating an open-loop unstable ball magnetic-levitation (maglev) system we constructed.
