| Abstract |
This paper compares the effectiveness of two control strategies for torque ripple reduction of interior permanent magnet synchronous motors with harmonics in both magnet flux and inductance. One strategy is current control and the other is direct torque control. For current control, two estimation methods for the instantaneous torque are introduced; a parameter-based equation in the rotating frame and a flux-based calculation in the stationary frame. The effectiveness of these schemes is examined. From simulation results, the characteristics of instantaneous torque for direct torque control and current control are discussed. |
