摘要
在分析线性滤波器原理的基础上，建立了化工系统动态信号的最优线性滤波器的数学模型，并以加氢裂化反应器出口温度信号的除噪为例比较了滤波器模型参数对去噪效果的影响。
Based on analysis of the principle of linear wave filter, a mathematic model of optimal linear wave filter was built to eliminate the noise from dynamic signal in chemical processes. Taking the noise elimination of the outlet temperature signal of hydrocracking reactor as an example, the effect of the model parameters of the wave filter for noise elimination was compared.
