A Study on the Repeatability of Slat Control in Motorized Venetian Blinds

In this study, the slat angle accuracy of a motorized Venetian blind was quantitatively analyzed through repeated measurements in response to specified control input values.Variations in slat angle were compared under forward, reverse, and alternating control conditions and analyzed using the overall dataset.Experimental results showed that the slat angle increased from 45.1 to 121.2 under forward rotation, from 42.6 to 118.4 under reverse rotation, and from 43.7 to 119.5 under alternating control.Across all measurements, the standard deviation was 11.4 at step 0 and decreased to 3.7 at step 12 as the control step increased.These findings confirm that the product maintains a certain level of control consistency, while highlighting the importance of accounting for slat control errors in practical applications.
