“BLIND” CORRECTION OF THE ME ASUREMENT DYNAMIC ERROR – SIMULATION INVESTIGATIONS OF THE SECOND-ORDER SYSTEM
Jerzy Nabielec
Abstract:
The paper presents a measuring system, which performs auto-correction of dynamic errors caused by its analogue input circuits. Input signal is used for selfidentification of the system parameters. Influence of sampling frequency and A/D converter resolution on the correction efficiency has been investigated. A range of the system analogue part parameters variation, which allows for the efficient correction, has been determined. A measure, which determines the effectiveness of correction as related to the measurement result without the correction has been introduced. Investigation has been carried out for the second-order inertial plants.
