The ability to perform real-time simulation electrical motor testing hinges upon the capabilities of a real-time, high-fidelity motor model. This model enables engineers to focus on performing precise testing, not on the workings of the system.
The following presentations describe two key elements in creating the most effective HIL simulators for electrical transportation.
OPAL-RT provides FPGA and Simulink-based electrical motor models, such as: PMSM, IM, SRM, BLDC, DC and AC. OPAL-RT is also well-known for the development of real-time models of atypical motors, as needed.
High motor fidelity provides engineers with richer harmonics results, realistic current saturation behaviors and accurate torque results, enabling higher test coverage and quality when testing electrical motor controls.
Mechanical dynamics generally run as much as ten times slower than electrical dynamics performed on CPU, significantly increasing user flexibility.
A complete HEV/EV ECU test coverage requires validation of controller behavior under fault scenarios on electrical motors and converters. The OPAL-RT solution enables the simulation of faults on many converters and motors, including:
OPAL-RT's high-fidelity motor solution includes a flexible and intuitive user interface. The interface enables users to visualize signals as with a real scope, define parameters for most electrical motor components and calibrate I/Os. The electrical motor user interface includes an easy-to-use Python scripting interface, enabling users to create comprehensive test sequences.
With almost two decades of research and development in real-time simulation and a wealth of hands-on experience in power electronics, OPAL-RT has created eFPGASIM, the industry’s most powerful and intuitive FPGA-based real-time solution. eFPGASIM combines the performance of high-fidelity digital simulators with the very low latency required for hybrid and electrical transportation testing and R&D.
