Communication Delay Compensation for Networked Control Systems Based on Pole-placement Design Method

In the context of Networked Control Systems (NCS), communication time delay strongly influences the Quality of Control (QoC) of process control applications. The goal of this paper is to propose a way to calculate the closed-loop communication time delay and we compensate this time delay using the pole placement design method in order to improve the QoC for CAN-based NCSs. We consider the implementation of several process control applications on a CAN network. Then we show the interest of the proposed method by comparing the QoC in case of time delay compensation and of without time delay compensation
