Abstract

The transmission delays in the networked control systems are inevitable and can degrade the system´s performance or stability. This paper has proposed an r-suboptimal H_infin controller for networked control systems with model uncertainty and network induced delay which is longer than one sampling period. The closed-loop system with structured uncertainties and long transmission delay is asymptotically stable. Simulation is applied to numerical examples with networked control show that the proposed method works well.
