In this article, the event-triggered multistep model predictive control for the discrete-time nonlinear system over communication networks under the influence of packet dropouts and cyber attacks is studied. First, the interval type-2 Takagi–Sugeno fuzzy model is applied to express the discrete-time nonlinear system and an event-triggered mode, which is capable of determining whether the sampled signal ought to be delivered into the unreliable network, is designed to economize communication resources. Second, two Bernoulli processes are introduced to represent the randomly happening packet dropouts in the unreliable network and the randomly occurring deception attacks on the actuator side from the adversaries. Third, under the assumption that the system states are unmeasurable, a multistep parameter-dependent model predictive controller is synthesized via optimizing one series of feedback laws for a given period of time, which leads to improved control performance than that of the one-step approach. Moreover, the results on the recursive feasibility and closed-loop stability related to the networked system are achieved, which explicitly consider the external disturbance and input constraint. Finally, simulation experiments on the mass-spring-damping system are carried out to illustrate the rationality and effectiveness of the provided control strategy.

具有丢包和网络攻击的网络非线性系统的事件触发多步模型预测控制设计

本文研究了丢包和网络攻击影响下通信网络上离散时间非线性系统的事件触发多步模型预测控制。首先,应用区间类型 2 Takagi-Sugeno 模糊模型来表达离散时间非线性系统,并设计了一种事件触发模式,该模式能够确定采样信号是否应该传递到不可靠网络中,节省通讯资源。其次,引入了两个伯努利过程来表示不可靠网络中随机发生的数据包丢失和攻击者在执行器侧随机发生的欺骗攻击。第三,在系统状态不可测量的假设下,通过在给定时间段内优化一系列反馈律来合成多步参数相关模型预测控制器,这导致比一步方法改进的控制性能。此外,还获得了与网络化系统相关的递归可行性和闭环稳定性的结果,明确考虑了外部干扰和输入约束。最后,对质量-弹簧-阻尼系统进行了仿真实验,说明了所提控制策略的合理性和有效性。得到了与网络化系统相关的递归可行性和闭环稳定性的结果,明确考虑了外部干扰和输入约束。最后,对质量-弹簧-阻尼系统进行了仿真实验,说明了所提控制策略的合理性和有效性。得到了与网络化系统相关的递归可行性和闭环稳定性的结果,明确考虑了外部干扰和输入约束。最后,对质量-弹簧-阻尼系统进行了仿真实验,说明了所提控制策略的合理性和有效性。
