摘要
对于极值调节控制系统,提出了一种简捷、高效、实用的自适应动态寻优方法,以解决在工业生产过程中必须准确地辨识极值调节控制对象线性部分的参数与阶数这一无法回避的难题。该文所提出的这种新的自适应动态寻优方法对极值调节控制对象线性部分模型的先验知识要求很少,只需要知道其线性部分可以近似为一个一阶惯性环节与延滞环节的串联,或者是一个二阶惯性环节与延滞环节的串联就足够了。这一新的自适应动态寻优方法不仅能自动辨识极值调节控制对象线性部分的参数,又能自动适应这些参数的漂移,因此简捷、高效、实用。
In this paper, a simple, convenient and practical self- adaptive dynamic optimizing method for an extremum value control system is presented to solve a never evading problem in practical industrial process by using the previous method. The problem is that accurate identification of the parameters of linear part in the extremum value control system is too difficult. The method in this paper only needs much less apriori information concerning the controlled plant. This new method can automatically not only identify the parameters of control plant, but also can automatically adapt to the drift of the parameters. So it is very simple, convenient and practical to be realized in the real industrial process.
