| Abstract: | The data packet dropout degrades the performance and network utilization of networked control system. Based on network utilization, a feedback scheduler is used to adjust the sampling periods for tasks of NCS and network resources. The integrated control-scheduling is realized and the total control performance is optimized. The emulation result shows its effective. |

| Keywords: | packet losses network utilization rate feedback scheduling real-time control |
