| 英文摘要 |
| This paper focuses on the issue of event-triggered control against stochastic cyber attacks for switched cyber physical systems. Cyber-physical systems are described as a form of switched linear systems. In order to conserve system
resources and alleviate network load, an event-triggered scheme is introduced, under which the sampled data from the
sensor is transmitted to the controller via the communication network when the defined error exceeds a given threshold.
And two different characteristics of stochastic cyber attacks are considered in the sensor-controller communication network.
Then, under cyber attacks and the designed event-triggered controller, a switched stochastic cyber-physical system model is
established. In addition, by utilizing the mode-dependent average dwell time method, the corresponding switching signal is
constructed. The mean-square exponential stability is guaranteed under the designed event-triggered controller and mode dependent average dwell time switching signal, and the controller gain is presented. Finally, an example is exploited to
verify the validity of the obtained theoretical results. |
