摘要
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.
