【Abstract】 For the long communication delay,network_induced noise and data packet dropout in networked control systems(NCS),a design procedure is presented for sliding mode multiple steps predictive controllers.First,the controller is described,which takes advantage of robustness of sliding mode control to deal with the network_induced noise and multiple steps predictive way to deal with time_delay and data packet dropout.Furthermore,the stability of the resulting closed_loop system is analyzed.Finally,for a DC(direct current) motor controlled through a network,the controller is designed by using the proposed approach,and the simulation demonstrats the effectiveness of the proposed design.更多还原
