 摘  要
 預測控制自提出至今已近三十年，在工業過程控制中取得了許多成功的應用，引起控制界和工業界的極大關注，已被公認為是工業過程最有前途的先進控制策略。目前，許多著名軟件公司均已推出了預測控制商品化軟件包，并在煉油、石化等行業推廣應用，預測控制在過程控制領域發揮了重要作用。但現有的預測控制軟件大都是嵌入在這些著名軟件公司開發的專用平臺上的，應用廠家必需購買專業平臺才能使用，價格昂貴，在我國只得到了有限的推廣，且有些情況下從國外購進的軟件不適用于國內生產邊界條件的變化，不能充分發揮其作用。為此，我們面向我國工業過程的實際情況，以中小規模裝置的先進控制為目標，基于PC 機平臺用VC++語言開發了預測控制的通用仿真軟件，可對控制系統進行綜合仿真，為進一步實現推廣應用奠定了基礎。

關鍵詞：預測控制，防真軟件，VC++語言

Abstract
 The forecast control from proposed until now in the recent 30 years, have obtained many success applications in the commercial run control, cause the control and the industrial world enormous attention, have been recognized for are the commercial run most promising advanced control strategies. At present, many famous software companies have promoted the forecast control commercialization software package, and in profession promotion applications and so on the refinery, petrification, forecast the control has played the vital role in the process control domain.
 But the existing forecast control software is mostly inserting in the special-purpose platform which these famous software company develops, can use using the factory essential purchase specialized platform, the price is expensive, only obtained the limited promotion in our country, also in some situations from the software which overseas purchases is not suitable for the home production boundary condition change, cannot play its role fully. For this reason, we face the actual conditions of the industrial process of our country, the advancements of small-scale devices of Israel and China are controlled for the goal, have developed the common artificial software cont.
