Modeling and States Observer Design for Networked Control Systems with Long Time-delay

摘要

Based on the Fuzzy fusion technology, this paper proposes a modeling approach for networked con- trol systems with network-induced long time-delay. The system with long control time-delay is transformed into the one without time-delay. By using the probability of time-delay appearance as membership degree, the global T-S fuzzy model is set up. According to the model, a states observer is designed and the disturbance arising from calculation is cancelled. Then the stability of the closed-loop system is analyzed and the conditions of asymptotic stability are proposed. The simulation results show that the method is effective.
