Additional Adaptive Controller for Mutual Torque Ripple Minimization in PMSM Drive Systems

Abstract This paper presents an additional adaptive current controller for mutual torque ripple minimization in PMSM. It is assumed that the basis of the control system is a conventional current control loop commonly used in vector control of the PMSM. No change in the structure of current loop is required, only access to the torque reference input is needed. Parameters of the additional controller are adapted directly by the derived adaptation law. Finally, the proposed control scheme is verified by means of simulations.
