卷积伏安法实验数据的自适应卡尔曼滤波 Ⅱ.重叠峰的分辨

The Adaptive Kaiman Filtering of Experimental Data in Neopolarography Ⅱ The Resoluton of the Overlapping Responses

本文着重探讨自适应卡尔曼滤波对卷积伏安法重叠响应信号的分辨能力。通过拟合实验数据表明,1:N 自适应卡尔曼滤波器与快速傅里叶变换和标准加入法相结合,用于补偿系统的模型误差和进行重叠峰的分辨,效果良好。应用于 Cd(Ⅱ)～In(Ⅲ)体系重叠峰实测数据的分辨,获得满意的结果。

This paper presents a new method for the resoluton of overlapping neopolaro- graphic peaks by the adaptve Kalman filtering together with fast Fourier transform smooth- ing and standard addition method.The neopoloarographic synthetic data test indicated that 1 :N adaptive Kalman filter can compensate for modelling errors of system and resolve over- lapped response signals.The method has been verified by Cd(Ⅱ)—In(Ⅲ)system.The re- sults showed that the method was satisfactory.
