Abstract
A computer system detects and controls a relative position of two rotating eccentric shafts. Processing circuitry calculates a lead motor quadrature current of a lead motor driving a first eccentric shaft; calculates a follower motor quadrature current of a follower motor driving a second eccentric shaft; determines in real-time a phase angle between the lead motor and follower motor quadrature currents; modifies a rotation speed of the follower motor so that it is equal to a rotation speed of the leading motor; and when the rotation speed of the follower motor is equal to the rotation speed of the lead motor, modifies the rotation speed of the follower motor to adjust the phase angle to be equal to a main target phase angle.
