Abstract This paper proposes a novel linear interpolation method for improving final output data interpolation error appliable in look-up table based PMSM drive. Conventional linear interpolation method is generally 2D-Interpolation method which has two input parameters. This 2D-Interpolation method uses constant unit torque for reducing DSP processing time, it has a problem when the interpolation process is performed with final torque output, interpolated output can not follow the torque reference. In this paper, a modified conventional interpolation method is proposed to remove torque control error of final torque output data.
