The control and scheduling for wireless networked control system with packet dropout and disturbance are investigated. A prediction based event triggered control is proposed to reduce data transmissions while preserving the robustness against external disturbance. First, a trigger threshold is especially designed to maintain the difference of the estimated and actual states below a proper boundary when system suffers from packet dropout. Then a predictive controller is designed to compensate for packet dropouts by utilizing the packet-based control approach. The sufficient conditions to ensure the closed-loop system being uniformly ultimately bounded are derived, with consequently the controller gain method. Numerical examples illustrate the effectiveness of the proposed approach.

研究了具有丢包和干扰的无线网络控制系统的控制和调度。提出了一种基于预测的事件触发控制，以减少数据传输，同时保留针对外部干扰的鲁棒性。首先，专门设计一个触发阈值，以在系统遭受数据包丢失时将估计状态与实际状态之差维持在适当的边界以下。然后，将预测控制器设计为通过利用基于数据包的控制方法来补偿数据包丢失。得出了确保闭环系统均匀最终受约束的充分条件，因此采用了控制器增益方法。数值算例说明了该方法的有效性。
