METHOD TO COMMAND AND CONTROL THE ELECTRIC MOTOR OF AN AUTOMATION UNIT AND CONNECTED SYSTEM

摘要

Method to command and control an electric motor (12) of an automation unit (10). The unit comprises a mechanical member (13) driven by a drive shaft (15) a central command and control unit (14) and a position detection mean (16). The method provides that the central command and control unit (14) receives the position signals of the shaft (15) of the electric motor (12) and/or of the mechanical member (13) from the position detection mean (16) divides the operating cycle into a plurality of sub phases ('n') equal with respect to each other consisting of elementary units and for each of said sub phases or multiple of sub phases selects predefined or self learnt current reference values and generates a signal consisting of an instantaneous current reference (feed forward) for the electric motor (12).
