In the dynamic process of detection, attention should be given to the dynamic errors in measurement caused mainly by the delay characteristics of sensors and transformers, This paper presents a kind of method of intelligent processing of signals carried by the variable values to be measured. The time constant Tm representing the delay characteristics is recognized on- line, The effect of the delay characteristics can be diminished or even eliminated by correcting or compensating so that the dynamic errors can be diminished or eliminated. The measured values of the variables will thus be enabled to rapidly and accurately trace the true values of the variables to be measured.
