碩士 === 義守大學 === 電機工程學系 === 88 === In recent years, the life cycle of industrial products becomes shorter and shorter ; the diversity and complexity of functionality are continuously increasing. Thus, conventional methods and techniques of industrial controller design can no longer satisfy the actual demands like smartness, miniaturization, short time-to-market, etc. This paper is devoted to elaborate a methodology for hybrid controller design and high-level synthesis, combining discrete time system(DES) and continuous time system(CTS). This methodology includes successively system analysis, DES specification, GRAFCET modeling, DES/CTS interfacing,VHDL-based synthesis and FPGA hardware realization. We took a drilling machine as an example to apply this structural and automatic design procedure and achieved high-level hardware synthesis, This example demonstrates integrated design and rapid prototyping of our methodology which are valuable for industries.
