Then some conclusions are gotten . with these conclusions , we design a motor control integrated circuit , and examine it by the soft of asic design . the motor control integrated circuit can provide improved performance 在此觀點的基礎(chǔ)上,設(shè)計了一種交流異步電機變頻調(diào)速控制集成芯片電路,并且,通過即ga的設(shè)計方法,對所設(shè)計的集成電路進行了功能性驗證。
The system is based on chopper constant current drive technique , according to the top level design idea , adopting advanced specical subdivision control integrate circuit and powerful function 80c196kc to organize the system frame , desiging the minimum system of single - chip microcomputer , multifunction i / o interface circuit , relay switch circuit , keyboard and display circuit , multifunction digital setting interface circuit and so on , utilizing the hso and hsi interface circuit which are owned by this single - chip microcomputer exclusively and its powerful command system to realize dual - degree switch control , automation orientation , automatically searching zero position , locking machine when stopping , frequency to set digitally , automatically adjusting speed through changing frequency , swithing subdivision or squarewave control , on the basis of above , the system also have the function of running according to the setting steps and the frequency , voltage and current to display through the led , etc 系統(tǒng)基于斬波恒流驅(qū)動技術(shù),按照頂層設(shè)計思想,采用先進的專用細分控制電路和功能強大的80c196kc單片機來組建系統(tǒng)構(gòu)架,設(shè)計了單片機最小系統(tǒng)、多功能i o接口電路、繼電器切換電路、鍵盤顯示電路和多功能數(shù)字設(shè)定接口電路等,利用該單片機獨有的hso和hsi接口及其強大的指令系統(tǒng),實現(xiàn)了雙余度混合式步進電動機的余度切換控制、自動定位、零位自動搜索、停機鎖定、數(shù)字化頻率設(shè)定、自動調(diào)頻變速控制、細分方波切換控制,在此基礎(chǔ)上,該系統(tǒng)還設(shè)有按預(yù)置步運行、 led頻率電壓相電流顯示等功能。
