Popis:	This paper presents a method to reduce torque ripple considering parameters with magnetic saturation. To estimate parameters of inductances for interior permanent magnet synchronous motor (IPMSM), the proposed method uses recursive least square (RLS) estimation algorithm. The estimated inductances are used for calculating torque and DC link voltage. Using the torque and the DC link voltage estimators, this control method can reduce torque ripple of IPMSM because of keeping linearity of inverter output. Therefore, the torque control system can achieve precise torque control. The proposed control method is verified by computer simulation and experiment.
