| Abstract: | This paper deals with three phase asynchronous motor variable frequency variable speed system with 8031 single ship micro-processor and HEF4752V large scale integerated circuit. By using this method, Computing time is saved and good system response is obtained.The real- time control performance of this system is good and electrical circuit is simple and reliable. It is preferable in the small and middle AC asychronous motor veriable frequency variable speed system. |
