具快速反應之高精密加熱系統之設計與實現

本研究主要是將合作廠商既有的設備，更改系統的內部控制，使用自製的溫度控制系統，實現快速溫度穩定的裝置。目前PID控制的研究與應用越來越成熟，許多研究文獻接著重於以不同的演算法搭配PID控制，其中用到的演算法包括模糊演算法、類神經演算法、基因演算法、灰色演算法和專家系統等。本篇論文採用了增量式數位PID控制，相較於傳統PID控制器，增量式PID控制器具有較快的穩定時間、較少的振盪等優點。在功能上市售的PID控制器必須額外加上記錄器材方可記錄資訊或是採用具有記憶卡或具有網路傳輸功能之人機介面，本研究自製PID控制系統則已經包含記錄與網路傳輸功能，同時控制介面使用的靈活度較大。本研究控制的部分使用了微晶片的系統，其採樣時間是微秒等級，而上市售PID採樣時間則為毫秒等級，因此在反應的靈敏度以及資料的運算量上，本研究控制器的能力都提高了許多。本研究產品的另一項優點為人性化設計，使用上更加便利，相信將成為加熱控制系統的未來趨勢。

In this study, The traditional control system were replaced with our homemade control system for the equipment of manufactures. Recently, research and application of PID control are more and more mature, a lot of research literatures were reported by using the PID control algorithm, including fuzzy algorithm and neural algorithms, genetic algorithms, Gray algorithmand expert system. This paper also adopts the incremental digital PID control, compared with the traditional PID controller, the incremental PID controller has the advantages of faster settling time, less oscillation, etc. In the PID controller functions listed for sale must be added to the recording equipment before the record information, or using a memory card or network transport functions of the human-machine interface, on the other hand, our studied self-made PID control system already contains the recording and network transmissionfunction control interface witha larger degree flexibility in operating.The control part of this study using a microchip system, and its sampling time is microseconds grade, compared to the millisecond rating listed for sale, in the computation of the sensitivity of the reaction, as well as information, the ability of the controllerhave improved a lot. Another advantage of this study is user-friendly design and more convenient to use, the design model believe willbe the future trend of the heating control system.
