This paper investigates the event-triggered control problem for networked control systems subject to deception attacks. An improved event-triggered scheme is proposed to reduce transmission rate by using both the information of the relative error and the past released signals. Under the proposed event-triggered scheme, a new switched time-delay system model is proposed for the event-triggered control systems. Based on the new model, the exponential mean-square stability criteria are derived by using the constructed Lyapunov function. Then, a co-design method is developed to obtain both trigger parameters and mode-dependent controller gains. Finally, the proposed scheme is verified by an unmanned aerial vehicle system.

本文研究了遭受欺骗攻击的网络控制系统的事件触发控制问题。提出了一种改进的事件触发方案，通过使用相对误差信息和过去释放的信号来降低传输速率。在提出的事件触发方案下，针对事件触发的控制系统提出了一种新的切换时滞系统模型。在新模型的基础上，使用构造的Lyapunov函数导出指数均方稳定性标准。然后，开发了一种共同设计方法来获取触发参数和与模式有关的控制器增益。最后，该方案通过无人机系统进行了验证。
