Popis: In this work, we deal with the problem of the Azimuth-Elevation (AE) blind tracking for the heliostats in solar central tower. The variation of the AE heliostat angular positions is supposed to happen in well-defined steps of time. It is the time necessary for updating the heliostat position where the mirror is kept properly aligned to the receiver situated on the top of the tower. We noted it here as the time necessary to update the position: TUP. This approach allows identifying the optimal rate of calculation of the new position and avoiding the arbitrary determination of TUP to reduce the number of motor interventions.
