Calibrating Optimal IPMSM Control Using Model-Based Calibration

Controlling the torque of an interior permanent magnet synchronous machine (IPMSM) 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, IPMSM control also requires calibration. Typically, during IPMSM calibration, motor characterization tests are conducted on the dyno, and motor data is collected to feed through a calibration workflow. This workflow calculates optimal id/iq combinations for IPMSM flux weakening and torque control.

Watch how to use statistical and optimization methods and Model-Based Calibration Toolbox™ to help design IPMSM characterization experiments and automate the calibration of optimal torque control id/iq lookup tables. This workflow demo was created using new features available in MATLAB^® R2023b.
