Computer system for detecting and controlling a relative position of two rotating eccentric shafts, vehicle comprising such a computer system, method, and storage medium for performing such a method

A computer-implemented method for detecting and controlling the relative position of two rotating eccentric shafts, the method comprising:

• calculating, by a processing circuitry of a computer system, a lead motor quadrature current of a lead motor, the lead motor driving a first eccentric shaft among the two eccentric shafts;
• calculating, by the processing circuitry, a follower motor quadrature current of a follower motor, the follower motor driving a second eccentric shaft among the two eccentric shafts;
• determining in real-time a phase angle between the lead motor and follower motor quadrature currents by the processing circuitry;
• modifying a rotation speed of the follower motor to be equal to a rotation speed of the leading motor by a closed loop control comprised in the processing circuitry;
• and
• when the rotation speed of the follower motor is equal to the rotation speed of the lead motor, modifying the rotation speed of the follower motor to adjust the phase angle to be equal to a main target phase angle by the processing circuitry.
