Quantized feedback for event-triggered control systems is addressed in this paper. The state of the controlled linear plant is sampled and quantized by a logarithmic quantizer upon an event-triggered scheme, then, the quantized data is transmitted and arrives at the controllers’ side along the network after a short time delay. Since event-triggered control can reduce the need for feedback, an event-triggered scheduler is concerned, which decides when continuous measurement state is sampled and quantized. Moreover, based on the event-based quantized feedback, the stabilization of the controlled plant is ensured. It is shown that the proposed event-triggering scheme is robust to quantized error and time-delay. Meanwhile, the minimum inter-event time is established to avoid Zeno behavior. An illustrative example is given to show the effectiveness of our result.

具有量化和时滞的线性系统的事件触发调度控制
本文讨论了事件触发控制系统的量化反馈。对数量化器根据事件触发方案对受控线性植物的状态进行采样和量化,然后,经过短暂的时间延迟后,量化的数据将被传输并沿着网络到达控制器一侧。由于事件触发的控制可以减少对反馈的需求,因此需要考虑事件触发的调度程序,该调度程序决定何时对连续的测量状态进行采样和量化。此外,基于事件的量化反馈,可以确保受控工厂的稳定性。结果表明,所提出的事件触发方案对量化误差和时延具有鲁棒性。同时,设置了最小的事件间时间以避免Zeno行为。
