On the Optimal Design of Hold-Zero Control for Networked Control Systems with Control Missing

Abstract : The admissible control missing rate (ACMR) of a sampled-data control system is an important index which reflects the stability robustness with respect to control missing in the network. In addition, ACMR can be used to design a hyperperiod, by which system resource can be saved. In this paper, we propose a switched hold-zero (HZ) control as a control-missing compensator. The switched HZ control has two control modes: the hold-control one and the zero-control one. The switching between two control modes is determined by a switching parameter. To obtain an ACMR as large as possible, we propose a method to optimally design the switching parameter. It will be seen that the switched HZ control can lead to larger ACMR than that derived by the existing method.
