Torque and Flux Weakening Control with MTPV for Interior Permanent Magnet Synchronous Motor

This paper proposes an improved stator flux control algorithm based on the torque feedforward control technique for interior permanent magnet synchronous motor (IPMSM). The proposed flux linkage control algorithm can prevent the d and q- axis voltages from saturation and improve the dynamic behavior. A lookup table is used in the torque feedforward control technique, which outputs the desired d and q-axis currents according to the two inputs: torque command and desired stator flux linkage magnitude. The method of constructing lookup table is mentioned. Simulations are carried out. The results prove the effectiveness of the proposed method.
