就工控系统中普遍存在的被控对象时变滞后的问题，本文介绍了一种将模糊原理应用于预估控制系统中的新型控制方法，它不依赖于被控对象自身的数学和物理特征，弥补了目前广泛采用的史密斯预估补偿控制方法和大林算法的不足，具有良好的控制品质和动态适应性，并得到了仿真试验的验证。

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。
