| Summary: | 碩士 === 國立臺灣海洋大學 === 電機工程學系 === 107 === The goal of this thesis is to improve the performance of a ready-made automatic
feeder. We try to resolve the problems that the feeder cannot provide precise feed
weight and cannot control the feeding location. In our approach, the feeding location
is determined by a stepper motor controlled by a PID controller. On the other hand,
by experiments, we control the feed weight by open-loop control. For reliability, the
controller is implemented by a PLC.
Key word: automatic feeder, PID controller, feeding, fixed-point feeding
