Rutledge還記得過程控制的早些時候，我們在米德紙業(yè)公司開始應(yīng)用過程控制造紙（現(xiàn)在是著名的紙業(yè)巨頭MeadWestvaco）。Rutledge是俄亥俄州Chillicothe米德研發(fā)部門做了35年，是主要的科學(xué)家。 在那其間，他對造紙的過程控制的貢獻(xiàn)是非常巨大的。Rutledge還在俄亥俄州和紐約的一些大學(xué)里教過數(shù)學(xué)和物理，同時繼續(xù)他在米德的職業(yè)生涯。 Rutledge說：“我們很熟悉IBM的控制運作，也熟悉一個在Cleveland的鋼鐵廠，并想象著能適用于造紙過程：用來染色、涂布、填料和其它造紙過程中的活動。還可被用于擴(kuò)展，通過在headbox中的變動漿流，從而控制性質(zhì)定量。” 這些信息由在卷軸上的性質(zhì)測量反饋到實驗室和控制器上。這些信息不僅僅是反饋或是前饋控制，還供研究所用。據(jù)Rutledge稱，這使得米德一舉成為造紙業(yè)強(qiáng)有力的競爭者，通過為市場提供高質(zhì)量的紙。 Rutledge隨后參與了第一個計算機(jī)控制的造紙機(jī)的安裝，在米德這也是第一個。 時間一天天過去，直到他1990年退休，Rutledge開始成為造紙行業(yè)中許多過程控制中有影響力的理論家之一，對造紙專業(yè)標(biāo)準(zhǔn)的貢獻(xiàn)是相當(dāng)大的。他對連續(xù)過程管理和分批過程管理都有巨大的貢獻(xiàn)，尤其是在添加劑的創(chuàng)造上。他是俄亥俄州紙漿座談會邁阿密大學(xué)的主要創(chuàng)始人和支持者之一，并獲得大學(xué)博士頭銜。 Rutledge畢業(yè)于俄亥俄州Hiram的Hiram學(xué)院，在二戰(zhàn)期間參加美國陸軍，并在Ann Arbor.的密歇根州大學(xué)獲得核子物理學(xué)哲學(xué)博士學(xué)位和理學(xué)碩士學(xué)位。所以，他的一個生都傾注于過程自動化專家，開始在現(xiàn)場做一些與典型事件完全不同的事情。 [FONT=times] original text [/FONT] [font=times][Color=#708090]In the early days of process control,” Wyman “Cy” Rutledge remembers, “we began applying this method to papermaking at Mead Paper Corp. （now MeadWestvaco）.” Rutledge was principal scientist for 35 years at Mead Research and Development in Chillicothe, Ohio. During that time, his contributions to controlling the process of papermaking were enormous. Rutledge also taught math and physics at several universities in Ohio and New York, while continuing his career at Mead. “We were familiar with the control work done by IBM and a steel company in Cleveland, and thought this could be applied to paper processes,” says Rutledge. “It was used for applying color, coatings, fillers and other additives in the papermaking process. Also it was extended to controlling the basis weight by means of a variable stock flow valve at the headbox.” The information was fed back to controllers and the lab from a basis weight measurement at the reel. This information was used for studies, not just for feedback or feedforward control. According to Rutledge, this enabled Mead to move ahead of its competitors by supplying higher-quality paper to companies like Hallmark. Rutledge then participated in installing one of the first computer-controlled paper machines, and the first one at Mead. Over the years, until his retirement in 1990, Rutledge became one of the most effective theorists of process control as applied to papermaking, and his contributions to professional standards bodies are considerable. He contributed both to continuous process management and to batch process management, especially in the addition of and creation of additives. He was one of the principal founders and supporters of Miami University of Ohio’s Pulp and Paper Symposium, and received an honorary doctorate from the university. Rutledge graduated from Hiram College in Hiram, Ohio, served in the U.S. Army during World War II, and earned both a M.S. and Ph.D. in nuclear physics from the University of Michigan at Ann Arbor. He is, therefore, another lifetime process automation professional, who initially set out to do something entirely different-a typical occurrence in the field. [/color][/font]
