Sanden improved the development of electric motor controls by introducing Opal-RT's hardware-in-the-loop (HIL) testing solution. MIL testing was accelerated to real time, cutting total parameter and model iteration time from half a day to minutes, and accelerating tuning and exploration of control strategies. Engineers doubled test coverage, safely validating edge cases such as compressor stall, voltage disturbances and inverter faults while using a minimal hardware setup. Decoupling software testing from hardware availability combined with test automation procedures, Sanden enabled early error detection and process acceleration. Total time savings reach to 2-3 months in the development and validation process.
