In this paper, a torque ripple reduction method is presented for PMSM controlled by the torque predictive control. The proposed
method, which predicts the duty ratio of the active stator voltage applied, makes it possible to relatively reduce the torque ripple in
the steady state as well as to remain the good dynamic response in the transient state. With the duty ratio prediction method, the
magnitude and time interval of the active stator voltage vector applied can be continuously controlled under the varying operation
conditions. Simulation results show validity and effectiveness of this work.
