基于模型的变门限状态反馈事件触发控制

针对基于模型的事件触发状态反馈控制系统, 提出一种触发门限可变的触发机制. 该触发机制能够在被控对象面临变化较大且快的干扰时, 自动调整触发门限变大, 避免频繁的事件触发导致网络通信资源浪费; 能够在被控对象面临变化较小的干扰时, 通过定时触发, 避免长时间没有事件发生导致的通信网闲置, 同时自动调整触发门限变小, 提升控制性能. 仿真结果表明, 较固定门限触发机制, 所提出的触发机制能利用更少的通信资源实现整体控制性能的提升.提升.

Model-based event-triggered state feedback control with variable threshold

An event-triggering mechanism with variable threshold for model-based event-triggered state-feedback control system is propoesd. When strong and fast varying disturbances act on the plant, this event-triggering mechanism can enlarge the threshold automatically to mitigate the unnecessary waste of communication resources. When slowly varying disturbances act on the plant, this event-triggering mechanism can avoid the communication network lies idle by using a timetriggering mechanism. Meanwhile, this event-triggering mechanism can also decrease the threshold automatically to improve the control performance. Simulation results show that, compared with the fixed threshold event-triggering mechanism, the proposed variable threshold event-triggering mechanism consumes less communication resources, but makes better whole performance.
