Composite Disturbance Filtering Algorithm and Realization for Slow Variation Signals
Biao Chen · Jisuanji yingyong yanjiu · 2002
The acquisition of signals in computer-based measurement and control systems is liable to making errors owing to the electromagnetic disturbance for the three varities: impulse, power frequency and random. Disturbance filering algorithms used to emphasizing particularly, not comprehensively. The algorithm introduced in this paper tries to filer all the three varities of disturbance. The algorithm is based on the self-designed improved LOR filter, added by an avarage processing. Simulation and practice results prove its validity and better precision.
