The developed unwinding machine is connected to the winding machine to follow the motion of the winding ma-
chine in the experiment.The proposed relative motion controller with minimum relative error control model is applied
I32 to the system to find out the following performance between the leading motor for winding spool of system A and the
following motor for unwinding spool of system E. This experiment involves the measurement of the positional variation
of the dancer roller and the speed of the winding and unwinding spool.
