针对离散时间线性系统，提出了一种输出反馈事件触发控制器。我们使用新的积极的系统，间隔观察员，事件触发的状态估计器，和触发时间，从估计值计算。这提供了一个离散时间模拟我们最近的正系统方法的连续时间系统。在我们的离散时间事件触发器中，一个关键的新成分是它们使用绝对值向量，而不是通常的欧几里得范数。我们说明了我们的方法使用事件触发的BlueROV 2水下航行器模型的好处。
We provide an output feedback event-triggered controller for discrete-time linear systems. We make novel use of positive systems, interval observers, an event-triggered state estimator, and triggering times that are computed from estimator values. This provides a discrete-time analog of our recent positive systems approach for continuous-time systems. A key novel ingredient in our discrete-time event triggers is their use of vectors of absolute values, instead of the usual Euclidean norm. We illustrate the benefits of our method using a model for event-triggered BlueROV2 underwater vehicles.
