This paper mainly investigates the application of the butterworth low pass digital filter in automatic measureing systems The necessity of applying the low-pass filter in those systems with high sampling rate and low output speed is discussed. In that way,the measurement noise can be decreased and the system resolution can be improved Compared with the conventional mult-point average filter, the butterworth filter has more satisfactory performances, and can be implemented with recursive algorithm, which needs...

This paper mainly investigates the application of the butterworth low pass digital filter in automatic measureing systems The necessity of applying the low-pass filter in those systems with high sampling rate and low output speed is discussed. In that way,the measurement noise can be decreased and the system resolution can be improved Compared with the conventional mult-point average filter, the butterworth filter has more satisfactory performances, and can be implemented with recursive algorithm, which needs less storage capacity of computer. The design method for determaining the parameters of butterworth low-pass digital filter is quite easy and convenient .The way for executing real -time filtering algorithm is provided, in which the high-order filter consists of several two- order filters in series and the first datum is used for repeatedly iterating many times, thus, the numerical instability is prevented successfully and the initial transient process is shortenedFinally, this paper gives a result of the application to the test of long-term gyro drift, which shows that the effect of low-pass digital filter is quite obvious. The signal of gyro drift with low-frequency property is truly conserved and the high-frequency noise from measurement circuit is basicly eliminated.

Kalman filter relies on a linear model consisting of two equations. However, an accurate model is difficult to obtain, thus measurement model errors can occur in multicomponent analyses. The adaptive Kalman filtering technique can estimate covariance R and compensate these errors. NPP and DPP synthetic data tests show that several first data of the data sequence cannot be zero when adaptive Kalman filter is used, and the estimation errors of adaptive Kalman filter are much smaller than the ordinary...

Kalman filter relies on a linear model consisting of two equations. However, an accurate model is difficult to obtain, thus measurement model errors can occur in multicomponent analyses. The adaptive Kalman filtering technique can estimate covariance R and compensate these errors. NPP and DPP synthetic data tests show that several first data of the data sequence cannot be zero when adaptive Kalman filter is used, and the estimation errors of adaptive Kalman filter are much smaller than the ordinary Kalman filter. We had used the adap tive Kalman filter to separate Cd (Ⅱ) /In (Ⅲ) overlapped responses. The innovation sequence shows that measurement model errors do exist in some portion of the volt—ammogram.

卡尔曼滤波器依赖于由两个方程组成的线性模型,在多组份分析时测量模型会存在误差,自适应卡尔曼滤波技术实时估计协方差R以补偿这种误差。本文在脉冲极谱分析法领域研究自适应卡尔曼滤波技术的应用.常规脉冲极谱和差分脉冲极谱的拟合数据试验表明,应用这种技术时,数据序列的初始几个数据不能是零;自适应滤波的估计误差远小于普通滤波的估计误差。用自适应卡尔曼滤波器分辨Cd(Ⅱ)/In(Ⅲ)重叠响应信号,新息序列表明,测量模型误差存在于Cd(Ⅱ)开始起波至峰值范围内.
