著重從農業信息化發展過程中市政府職能的發揮，信息服務體系建設，農業信息化人才和軟體建設等方面入手，深入研究和綜合分析了煙臺市農業信息化的制約因素：主要存在著各級領導對農業信息化的重視程度不夠，投入不足；農業信息網路人才缺乏，農民對信息化的認識和利用不足；信息發布、傳輸滯后且實用性不高；農業信息網路體系不夠完善，整體服務水平不高；政府缺乏宏觀調控，農業信息資源整合程度不夠等制約因素。First, because pipelines are so complex that controlled object is high order, delay, coupling, nolinear and time - varing, it is difficult to realize closed loop control for it using valid mathematic model. to resolve this problem, the paper presents a fuzzy - pid control algorithm with self - adjusting regulation factor. second, if a moving motor supplied by inverter power is switched to be supplied by power supply, the impact of overload - voltage and overload - current appears
主要針對中、大容量供水系統中，由於供水管網鋪設復雜、彎管多、控制對象具有高階、滯后、耦合、非線性及參數時變的特點，難以利用有效的解析式數學模型進行閉環控制，以及多臺水泵並聯運行時，水泵電機由變頻電源供電向工頻電源供電切換過程中產生的過電壓過電流沖擊這兩個難題，提出了可調整因子fuzzy - pid控制演算法及利用鎖相環控制實現水泵電機由變頻電源向工頻電源的同頻同相平滑切換。
