一类弱化缓冲算子研究

Study on a Class of Weakening Buffer Operators

根据灰色系统理论的差异信息原理和新信息优先的原理,针对缓冲作用过强过弱的问题,客观地构造出一类新的弱化缓冲算子,并研究其特性,有效地解决了冲击扰动系统数据序列在建模预测过程中出现的定量预测结果与定性分析结论不符的问题.实例分析结果表明,这类弱化缓冲算子实用又有效.

Based on the principle of difference information and new information priority of gray system theory, in view of the problem that buffer is too strong or too weak, a new class of weakening buffer operators are made objectively, and their characters are studied. The problem of some contradictions between quantitative analysis and qualitative analysis existing in pretreatment for vibration data sequences is solved effectively. An example shows that the class of new weakening buffer operators are practical and effective.
