在基于数据包的网络控制系统框架下，提出了一种误差有界的传感策略。该策略通过仅允许满足某些预定传输规则的感测和控制数据分组的传输来减少传感器到控制器和控制器到致动器信道中的数据传输。通过将其融入基于分组的网络控制系统控制框架中，该策略可以在保证系统性能的同时达到减少通信资源使用的目的。在此框架下设计了稳定控制器，并研究了该方法对系统稳定性的影响。数值和实验结果表明了该方法的有效性。
An error bounded sensing strategy is proposed within the packet-based control framework for networked control systems (NCSs). This strategy reduces the data transmissions in both the sensor-to-controller and the controller-to-actuator channels by allowing the transmissions of only the sensing and control data packets that satisfy some predetermined transmission rules. By fitting it into the packet-based control framework for NCSs, this strategy can achieve the goal of reducing the use of the communication resources while at the same time maintaining the system performance at an acceptable level. Stabilized controllers are designed within this framework, and the effects on the system stability brought by this approach are also investigated. Numerical and experimental examples illustrate the effectiveness of the proposed approach.
