摘　　要：以智能阀门为被控对象,以经典Z-N法、CHR法、IMC法及Cohen法为PID自整定的方法,通过萃取多种评价指标,用熵的方法来确定评价指标的权重,对上述各种方法进行评价。获得的权重具有动态化、客观化以及科学化等特点。将熵确定权重的方法应用于智能阀门定位器PID自整定的评价中,得到了科学、合理的评价结果,满足了工业需求。Taking the intelligent valve as controlled object, we can use various PID Auto-turning methods, such as Z-N, CHR, Cohen-Coon and IMC method, to evaluate the PID auto-turning results. Extract evaluation indexes and use the entropy to get the weight of the indexes. Then evaluate these PID auto-turning methods. The result of the weight is dynamic, objective and scientific. Using the method of entropy weight is reasonable and satisfy the needs of industrial applications.
