According to the system technology require, adopting singlechip realize open loop digital control of hdclsm ; using v / f conversion and complex key - control method realize digital setting of system parameter, such as velocity ; using micro - stepping control insure the motor running more smoothly ; adopting debasing speed control method to eliminate the mechanical impact of distance termination effectively ; at the same time, analyzing main power circuits drive circuit and protect circuit of system, completing hardware design and facture and software programming and debugging ; at last, making a whole test in hybrid rotary step motor. the experiment result indicates that this control system reaches the qualities required and run smoothly also
根據系統技術要求,採用單片機實現了混合式直流直線步進電動機的開環數字控制;
利用v f變換和復合鍵控方法實現了系統轉速等參數的數字設定;
利用細分控制技術保證了電機運行的平穩性,並進行了波形分析和理論研究;採用單片機軟體降速控制策略解決直線步進電機行程
末端的機械沖擊問題;同時對主功率電路、驅動電路和系統保護電路進行了分析,完成了硬體設計、製作和軟體編程、調試,最後在混合式旋轉步進電動機上進行了全面測試。

利益,自身還在蘇東劇變大潮的沖擊中發生著深刻的體制變遷,與政治、經濟危機相伴而來的民族危機最終導致國家分裂,並引起一系列愈益慘烈的武裝沖突和戰爭,威脅著巴爾干半島和歐洲的安全與穩定。
First, a terminal double bond was introduced into 3 - amino - 9 - ethylcarbazole ( aec ) via methacryloyl chloride to obtain the compound, 3 - ( n - methacryloyl ) amino - 9 - ethylcarbazole ( mec ). second, mec was copolymerized with butyl methacrylate to prepare the mec - immobilized polymer particles. the resultant polymer particles were used as a fluorescence probe, which was almost free of dye leaching, and had higher photostability in comparison with free aec
