Research Of The Application Of Petri Net Theory In Electric System

Petri Net is a powerful modeling tool for asynchronous concurrent systems.It's meaningful to apply the Petri Net theory to the real electronic system,since it takes advantages in solving the asynchronous concurrent problems.In this paper,firstly it establishes two Fault Diagnosis methods which are based on the Petri Net.Then it applies the Petri Net theory to digital circuits and provides a unified method which analyses Synchronous Circuits and Asynchronous Circuits.By analyzing the design of Parallel Controller for Capacitor charging and discharging circuit,it provides the idea to design Parallel Controller which Based on the Petri Net.It applies Petri Net modeling method to Digital- analog hybrid circuits for the first time.Also it demonstrates the control method of hybrid Petri Net,while it analyses its modeling abilities.After that, the paper introduces Matlab which helps the continuing development,which is a new way to design and realize Parallel Controller.The third step,it provides a hardware implementation method:Simulating Petri Net via hardware Description Language, getting source files,developing tools based on the EDA software,processing of Compile, simulation,adaptive and loading down to devices.
