(57) Covering apparatus (1) which comprises a plurality of covering blades (10), and movement
means (12) operatively connected to the covering blades (10) in order to actuate the
movement thereof. Such movement means (12) comprise at least one electric motor (25)
mechanically connected to the covering blades (10), and an electronic control unit
(26) operatively connected to the electric motor (25) in order to control the operation
thereof. More in detail, the electronic control unit (26) comprises: an acquisition
module (29) operatively connected to the electric motor (25) and configured for acquiring
first values of a first operating electrical parameter (i(t)) of the electric motor
(25) in at least one operating travel of the covering blades (10); a processing module
(32) configured for calculating, as a function of the first values of the first operating
electrical parameter (i(t)), corresponding values of a position parameter (xP) indicative
of corresponding operating positions of the covering blades (10) in the operating
travel; a control module (33) operatively connected to the electric motor (25) in
order to send, to the latter, a drive signal as a function of the aforesaid position
parameter (xP).
