摘　　要：在信号分析与处理中,为获取信号中反映其特征的有用成分,常采用滤波方法去掉干扰成分。针对在工业控制领域数据分析与处理问题,提出基于组合积分系统滤波算法。分析数字滤波器滤波原理,由组合积分环节均值滤波本质,设计组合积分系统滤波算法,实现低通、高通、带通滤波的功能。利用Simulink建模仿真,实验结果表明,该设计效果良好,表明所提方法的可行性及有效性。In signal analysis and processing often use filtering methods to remove the interference components in order to get the useful composition which can reflect the signal features. For data analysis and processing in the field of industrial control, propose a filtering algorithm based on combined integrating control system. Analysis of digital filter principle, by the combination of integral average filtering essence, design based on the combination of integral system filtering algorithm, realize low-pass, high-pass, band-pass filtering functions. Using Simulink modeling and simulation, the experimental results show that the design effect is good, shows the feasibility and effectiveness of the proposed method.
