Abstract :
As the control system scale develops, the application of the control network has increased. Due to the bandwidth constraint and the unreliable transmission of network, the time-delay and data-packet dropout exist inevitably in the networked control system. A novel compensation scheme is presented for the data-packet dropout. An open-loop estimator and a closed-loop estimator are designed according to whether the data-packet dropped. The result of the simulation shows the validity of the proposed design method.
