Transmission Times Reconstruction in a Telecontrolled Real-Time System

Abstract

The objective of this article is to present the reconstruction of the transmission times existing in the real-time systems telecontrol process, based on digital filtering methods, specifically the Kalman filter, applied to a set of measured values ​​obtained through the use of a workbench designed for remote systems telecontrol. For the success of reconstruction of the measured times, it was important to ensure the level of dependence of the random variables by characterizing the transmission times. As a final result, a successful reconstruction was obtained that was validated using some descriptive measures as the first and second moment of probability, as well as the quadratic error to verify this affirmation. This allowed us to conclude that the reconstruction technique is acceptable to characterize the dynamics of this temporal constraint.
