工业控制中接口处理器时序匹配优化设计

摘要

This article proposes a method for timing sequence matching of interface processor in industrial control.The method confirmed feature structure of timing sequence of different interface via building heuristic rule,fuzzy set,and subordinating degree function in part of processing of fuzzy timing sequence.Then it built a multivariate auto-regression model with multiple hidden period of characteristic factor of timing sequence signals.The method also reconstructed the phase space of transmit signal of each embedded port integrated with chaos theory anddesigned classifier of vector machine.Simulation shows that the method has high analysis precision and can provide a powerful gist for ensuring design quality of industrial control.%在工业控制中,对接口处理器时序匹配的设计,可以更好的提升工业控制的整体性能.对接口处理器的时序进行匹配,需要建立各个接口信号的特征空间,设计向量机分类器,完成对接口处理器的时序匹配.传统方法先建立时序的序列值之间的线性关系,进行多分辨率的数据挖据,但忽略了设计向量机分类器,导致时序匹配精度偏低.提出基于混沌的工业控制中接口处理器时序匹配方法.该方法在模糊时序处理部分通过建立启发式规则、模糊集合和隶属度函数,确定不同接口时序特征结构,建立接口时序信号特征因素多重潜周期多元自回归模型,融合于混沌理论重构了嵌入式各个接口发射信号的相空间,设计向量机分类器,利用该分类器完成对工业控制中接口处理器时序匹配.仿真证明,所提方法分析精度高,可以为保障工业控制设计质量提供有力的依据.
