High Fidelity Motor Modeling for HIL with FPGAs

Real-time capabilities are drastically increasing what testing can be done for electric powertrains. Important physical effects such as spatial harmonics and high-speed switching of wide bandgap devices can be achieved in the same model. Additionally, you can run these models in parallel with virtual vehicles. This allows you to connect the device under test (DUT), the motor controller in this example, with a virtual or real ECU for expansive test coverage. You can also use these same techniques to implement virtual dynamometers if ECU integration is unnecessary. See how the approaches presented are hardware agnostic and can often take advantage of existing lab equipment.
