Compensation of dynamic measurement error for sensors with measurement noise
Liu Qing · Journal of Jiangsu University · 2006
A dynamic compensation unit is connected to output port of sensors in series for improving the characteristics and compensating dynamic measurement error of sensors.The unit is a band-pass filter or a high-pass filters.It can eliminate dynamic measurement errors,but cause severe noise amplification.In order to solve this problem,a new method that compensates dynamic measurement error of sensors with measurement noise is proposed.The coefficient of the unit is obtained via experimental data.At the same time,a hybrid filter that combines polynomial prediction filter and median filter for denoising is employed.The method is proved to be effective by the simulation experiment.
