| This thesis is based on the project "Intelligent Control Theory and Method Research on Networked Control System (NCS)" which is funded by the National Natural Science Foundation. First, recent research progress on networked control system are introduced. Then, the controller design approach of state feedback and output feedback are proposed to stabilize NCS when network-induced delay is less than one sample period and may be more than one sample period, respectively. By using linear matrix inequality (LMI) approach, the sufficient conditions of robust stability for closed-loop NCS and the corresponding controllers design method are presented. Finally, the prospect of NCS and some issues that should be solved are pointed out in this thesis. |
