In manufacturing field, testing control algorithms can be time-consuming, expensive and potentially unsafe. To remain competitive, to reduce time to market and to deliver high-quality and reliable control systems, test engineers have replaced traditional testing methods with Hardware-in-the-Loop (HIL) testing, in which the plant to be controlled is replaced by models running on a real time computer and connected to the physical controller by specific IO board. A HIL based on a commercially available National Instruments NI platform has been developed to simulate a Permanent Magnet Synchronous Motor to test the response of an Electric Vehicle Control Unit (EVCU) under test.
