Controlling the torque of a permanent magnet synchronous machine (PMSM) to achieve high levels of accuracy and efficiency is one of the most important targets in high-performance electrified powertrain design. Just like IC engine control, PMSM control also requires calibration. Typically, during PMSM calibration, motor characterization tests are conducted on the dyno, and motor data are collected to feed through a calibration workflow. This workflow calculates optimal id/iq combinations for PMSM flux weakening and torque control. Watch how to use statistical and optimization methods to help design PMSM characterization experiments and automate the calibration of optimal torque control id/iq lookup tables.
