ABSTRACT:
A method for controlling in an open-loop voltage mode a DC motor driven through a power amplifier includes generating a control voltage for the DC motor to be input to the power amplifier based upon a difference between an external command and a correction signal, and amplifying the control voltage for generating a replica of an output of the power amplifier. A model of the DC motor is defined based upon electrical parameters of the DC motor. The method further includes estimating current flowing in the DC motor based upon the replica of the output of the power amplifier and the model of the DC motor, and generating the correction signal proportional to the estimated current.
