本文研究了传感器和控制器之间存在时不变时钟偏差的网络控制系统的镇定问题。时钟偏移被建模为参数的不确定性，我们提供了一个单一的控制器，能够稳定在给定范围内的每个时钟偏移的闭环存在的必要和充分条件。对于标量系统，我们得到的偏移间隔的最大长度，系统可以稳定的一个单一的线性时不变控制器。我们比较了偏移量的界限，将允许由特定类别的控制器的标量系统。
We consider the stabilization of networked control systems with time-invariant clock offsets between the sensors and the controllers. Clock offsets are modeled as parametric uncertainty and we provide necessary and sufficient conditions for the existence of a single controller that is capable of stabilizing the closed loop for every clock offset in a given range. For scalar systems, we obtain the maximum length of the offset interval for which the system can be stabilized by a single linear time-invariant controller. We compare the offset bounds that would be allowed by specific classes of controllers for scalar systems.
