| Summary: | 碩士 === 國立高雄應用科技大學 === 工業工程與管理系碩士在職專班 === 106 === This study applied the DOTP process temperature control process, the choice of temperature control valve opening to improve PID single loop temperature control time is longer, first of all, by PLC program will be heating process time cut into 7 segments, according to the various stages of heat demand different, the heat source opening should also be accompanied by changes, by Taguchi method to choose the optimal heat of each stage of the opening to optimize the temperature curve to shorten the process time, the operating conditions of each stage may be implicated in each other, the previous phase of improper operation will be Indirectly affect the next stage of warming, especially boiling stage, to grasp the appropriate opening of each stage, to help reduce the heating cycle time, in order to solve the above problems, The results of the study showed that Taguchi method was used as the basis, and Taguchi L8 (27) experiment design was adopted and PLC and graphical control program to collect Structured process information, then analyze the establishment of process performance indicators ( best parameter combination A2 , B1 , C2 , D1 , E2 , F1 , G2 ), and increase productivity and the production capacity was increased to achieve satisfactory results.
