在事件触发控制中,经常会出现控制输入必须稀疏的情况。因此,在这项研究中,我们提出了稀疏事件触发控制,这意味着控制输入是稀疏的,并以事件触发的方式更新。首先,我们提出了一种基于模型的方法,用于线性系统的稀疏事件触发控制,其中事件条件由李雅普诺夫函数定义。所得到的控制输入被证明是稀疏的,控制系统被证实是渐近稳定的。其次,我们将其扩展到数据驱动的版本,其中事件条件从状态轨迹上的在线数据自适应更新。最后,我们讨论了我们的框架扩展到两种情况下的干扰和非线性动力学的可能性。
In event‐triggered control, a situation where the control input must be sparse often arises. Therefore, in this study, we propose sparse event‐triggered control, meaning that the control input is sparse and updated in an event‐triggered manner. First, we present a model‐based method for sparse event‐triggered control of linear systems, where the event condition is defined by a Lyapunov function. The resulting control input is proven to be sparse and the control system is confirmed to be asymptotically stable. Second, we extend it to a data‐driven version, where the event condition is adaptively updated from online data on the state trajectory. Finally, we discuss the possibility of extending our framework to two cases of disturbance and nonlinear dynamics.
