Abstract
A control system () for controlling a brushless electric motor () for an automotive power actuator (), having a rotor () operable to rotate with respect to stator windings (), the control system () is provided with: a position sensing unit (-) coupled to the rotor (), to sense its angular position and to provide a sensed position (θ); and a generation unit (), to generate driving voltages and/or currents for the stator windings (), as a function of the angular position of the rotor (). A position estimation module () is coupled to the position sensing unit (-), to receive the sensed position (θ) and to correct the value of the sensed position (θ), thereby providing a corrected angular position (θ) to the generation unit ().
