本文是以數位訊號處理器DSP(Digital Singal Processor)之核心架構為主體的數位式溫度控制器開發,而其主要分為硬體電路與軟體程式兩部分來完成。而就硬體電路來看分為量測電路模組、DSP周邊電路及RS232通訊模組、輸出模組三個部分,其中在輸出上可分為電流輸出、電壓輸出以及binary command給加熱驅動裝置, RS232 除了可以與PC聯絡外也可以與具有CPU的熱能驅動器做命令傳輸。在計畫中分析現有工業用加熱驅動裝置和溫度曲線的關係,並瞭解其控制情況。軟體方面即是溫控器之中央處理器程式,亦即DSP控制程式,其中包括控制理論、感測器線性轉換程式、I/O介面及通訊協定相關程式。在控制法則上,提出一個新的加熱體描述模型,然後以前饋控制為主並輔以PID控制,得到不錯的控制結果。
