摘要
控制系统功能表图(CSFC)建立在Petri网的理论基础之上,用来描述控制系统的功能与特性,是一种并发系统的模型。文章介绍了如何用D触发器实现CSFC中的步,用与或门实现CSFC中的转换,并将基本电路封装成元件,存入EDA软件工具的库中以备调用。最后通过一个CSFC控制器,对D触发器和RS触发器实现方法进行了比较,并给出了仿真波形。
Control System Function Chart-CSFC is a model of parallel systems to describe the function and character of controlled systems ,which is a class of Petri nets. The article introduces how to implement the step of CSFC with D flip-flop, carry out transition in CSFC with and/or gates and package the basic circuit into components ,then keep them in the library of EDA software tools for use when needed .Last, the design methods based on D flip-flop and RS flip-flop are compared to a controllor based on CSFC by simulation.
