Abstract : This paper investigates the input-to-state stability (ISS) of continuous-time networked control systems with model uncertainty and bounded noise based on event-triggering. The information generated at the sensor is quantized and transmitted to the controller through a digital communication channel, which suffers from the network-induced time delay and clock offset. In the concerned event-triggering framework, such the clock offset may cause long-term inconsistency between the state estimates of the sensor and the controller, and leads to the failure of ISS. By designing a well-designed state-dependent event-triggering threshold and updating methods, it can still ensure ISS for the concerned system in the presence of bounded clock offset and model uncertainty without exhibiting Zeno behavior. Simulations are done to verify the achieved results.
