Testing control algorithms can be time-consuming, expensive, and potentially unsafe if you decide to test against the real system. To remain competitive and deliver high-quality controller software, test engineers have replaced traditional testing methods with Hardware-in-the-Loop (HIL) testing.
Hardware-in-the-Loop testing lets you verify your controller design without the complete system hardware. Rely on a real-time plant simulator that acts as a digital twin of the whole system or parts of the system to benefit from practicality and lower costs.
Safely test corner cases, integrate new hardware upon availability, and make controller design changes when they are still cost-effective to implement.
