An outlook on the dynamic error "blind" correction for the time-varying measurement channel

The paper presents the measuring system, which allows for correction of dynamic error caused by the analogue signal transducers, whose dynamic characteristics are changing with a rate approximate to the rate of change of the measured signal. Three methods for self-identification of the coefficients of the transducers´ dynamics model, using exclusively the measured signal at the transducers´ operating locations, are proposed. Analytical justification for the correctness of the proposed methods is presented for both: the special case of measuring periodic signals and for the general case when the measured signals are nonperiodic. The self-identification and correction procedures are performed as the algorithms processing the data collected from transducers.
