就工控系統(tǒng)中普遍存在的被控對象時(shí)變滯后的問題，本文介紹了一種將模糊原理應(yīng)用于預(yù)估控制系統(tǒng)中的新型控制方法，它不依賴于被控對象自身的數(shù)學(xué)和物理特征，彌補(bǔ)了目前廣泛采用的史密斯預(yù)估補(bǔ)償控制方法和大林算法的不足，具有良好的控制品質(zhì)和動(dòng)態(tài)適應(yīng)性，并得到了仿真試驗(yàn)的驗(yàn)證。

Abstract：As for the quality of delay and time-varying of controlled object widely exists in most industrial systems，this paper set forths an new method，which applies the theory of fuzzy into prediction control system。The method is independent of the mathematic and physical character， redeems the defect of conventional Smith prediction control and Dalin algorithm widely exploited at present and has an excellent performance and wonderfully dynamic adaptability which have been tested by experiment。
