本文讨论了用状态观测器观测不可测输入变量的问题,运用多项式近似作为不可测输入的动态数学模型,给出这种不可测输入观测器的存在条件和一种简易判别方法,讨论了多项式项数对观测结果的影响。文章还给出了催化剂循环量实时观测的应用实例。
This paper discusses the problem of observing unmeasurable input variables with state observers. By using polynomial approximation as a dynamic mathematical model of unmeasured inputs, the existence conditions and a simple discriminant method of this unmonitored input observer are given. The polynomial terms The effect of number on the observation result. The article also gives examples of real-time observation of catalyst circulation.
