[W-MB-152] Accuracy of Motor Plant Model Required for ECU testing
ECU testing is performed under various conditions from the normal to the abnormal system. Furthermore, both the torque and rotation speed are tested in a wide region in the driving state of the motor. Normally, DQ models that do not account for spatial harmonics are often used in ECU testing. However, there is a risk that the accuracy of the plant model is insufficient causing incorrect testing when the design margin is reduced by miniaturization and high output of the motor, or when gain adjustment is performed aiming at high responsiveness. This white paper explains the accuracy of the plant model required for ECU testing and presents examples. This paper shows the need to account for voltage limitation in steady torque control, load step response in speed control, and account for the effect of spatial harmonics when determining instantaneous interruption.

JMAG Open Interface

We have updated our site introducing case studies of linked analysis.
In recent years, the sophistication of electrical equipment design is required. As known there is a limit to the design of magnetic circuits alone, therefore multifaceted evaluations such as structure, vibration, heat, and control are required at the same time.It is more efficient to perform coupled analysis by linking different software where they have their own strength in the respective physical phenomenon rather than to adhere to one CAE software.

Case Studies
On the same page, we also introduce case studies from JMAG Users Conference Proceedings every week.
Case Studies of the Week:
Model-based development (MBD) is required in complex and large-scale systems such as aircraft. In this case study, MIL/HIL and actual machine verification are compared in motor drive system development. MATLAB/Simulink is used for modeling the entire system, PSIM is used for the inverter and JMAG-RT is used for the physical model of the motor.

Please check the case studies on the site above.
