Abstract
An electrical drive control system includes a controlled drive, an auxiliary generator, a control unit, and a power unit. The rotors of the controlled drive and of the auxiliary generator are connected so that rotation of controlled drive causes a corresponding rotation of the auxiliary generator. The control unit receives a first reference signal having a first frequency. The auxiliary generator receives a second reference signal having a second frequency. The control unit may generate the second reference signal. In response to the second reference signal, the auxiliary generator generates a primary information signal having a phase shift that is indicative of the rotational position of a rotor of the auxiliary generator and the controlled drive. The control unit receives a user selected position command indicative of a selected position of the rotor. In response to the difference between the selected and determined positions of the rotor, the control unit generates control signals for controlling the power unit to adjust the drive signal to the controlled drive.
