Current harmonic suppression for permanent magnet synchronous motors
This paper deals with problem of current harmonic suppression in permanent magnet synchronous motors (PMSM) First, the current harmonic model is considered in details in the dq coordinate frame. Then the current harmonic observer design is proposed to estimate online all harmonic components. Based on the harmonic observer, current harmonics are suppressed to obtain accurate currents. Finally, we present some simulations and experiments to validate the algorithm performance.
