A Study on Tuning PI Parameters Based on Communication Delay Time for Small DC Motor Control System through IP Network

摘要

In tuning PI controller for a DC motor control system through IP network, it is needed to know dead time in the system, although delay time is fluctuated. In this work, we study an approximate value of dead time when controlling through networks varying under exponential and log-normal distributions. As a result, it has been found that the first quartile can be approximately expressed as the dead time in cases that standard deviation is small.
