| 摘 要： | 针对基于模型的网络控制系统缺乏应对动态变化的网络负载问题,设计反馈调度器,依据实际的网络拥塞情况,调整基于模型的网络控制系统的状态更新时间.为应对状态不完全可测的情况,在控制结构中使用了状态观测器,并证明了所提出系统在可变更新时间情况下的稳定性.仿真结果验证了稳定性条件的正确性和新网络控制系统结构的有效性.

| Abstract: | A feedback scheduler is proposed for model-based networked control systems to cope with the flexible network load.The state update time is adjusted according to the real-time network congestion situation.State observer is used under the situation when the state of the controlled plant couldn't be acquired.The stability criterion of the proposed structure is proved under varying state update time.Simulation results illustrate the effectiveness of the stability condition and the novel control structure. |
