In this paper, the time-delay is considered when process equipment is controlled by a wireless network in a large-scale plant. To prevent a decline of a control performance by the time-delay, the time-delay compensation controller is designed. What's more, the experimental environment which simulates the remote control is made, and the effectiveness of the designed control system is confirmed by simulation...
