This brief adds dynamic variables to decentralized periodic event-triggered control (DPETC), denoting dynamic DPETC (DDPETC) for wireless cyber-physical systems whose sensors are distributed and bandwidths are limited, and studies the stability and L2-gain. In DDPETC, dynamic variables that require only local information are designed and added to the event-triggered mechanisms (ETMs). This dynamic variable can guarantee that the ETMs still be localized which does not require information from other nodes. For implementations with DDPETC, at each periodic sampling time the ETMs decide events based on new measurements from local sensors. Those measurements that trigger the events are transmitted to controllers, and after network transmission delays, they are received and the controller computes the control actions. The transmissions of these control actions from controllers to actuators are also decided by ETMs. The feasibility of the approach is shown via two examples. Numerical results show that, with the same stability and performance, DDPETC can save more than 40% events, making it more suitable for wireless cyber-physical systems.

无线网络物理系统的动态分散周期性事件触发控制


本文将动态变量添加到分散周期性事件触发控制（DPETC）中，表示传感器分布且带宽有限的无线信息物理系统的动态DPETC（DDPETC），并研究了稳定性和L2增益。在DDPETC中，设计了仅需要本地信息的动态变量并将其添加到事件触发机制（ETM）中。这个动态变量可以保证ETM仍然是本地化的，这不需要来自其他节点的信息。对于 DDPETC 的实现，在每个定期采样时间，ETM 根据本地传感器的新测量结果决定事件。那些触发事件的测量结果被传输到控制器，并且在网络传输延迟之后，它们被接收并且控制器计算控制动作。这些控制动作从控制器到执行器的传输也由 ETM 决定。通过两个例子说明了该方法的可行性。数值结果表明，在同等稳定性和性能的情况下，DDPETC可以节省40%以上的事件，更适合无线信息物理系统。
