碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 98 === This thesis would solve the control problem of the contiguous tape which using Reel-to-Reel winder mechanism to load and unload. In the past, some theses solve the speed matching between motors by using specific motor controller or specific mechanism. These designs are too complex and inflexible to suit the variety requirement. In this thesis, I have only used simple vibration mechanism. I hope that the variety requirement could be suited by turning the software. I have compared those results by using different algorithms and different type of sensors. According those results, I wish to find a better control method. During the experimenting, I found that the discontinuous sensor, like Photo-interrupter can not provide enough information about the vibration mechanism. The controller can not turn the motor speed in a short time. In opposition, when using the continuous sensor, like potentiometer can provide more information including the speed and the location of the vibration mechanism. It even provides the moving direction and acceleration. The controller can tune the motor speed by using typical PID control algorithm. I tuned the P、I and D parameter by the method provided by Ziegler & Nichols. When working in the factory, there is no problem!
