Hardware-in-the Loop Simulation for Testing of Condition Monitoring and Fault Diagnosis Algorithms for a Scrubber Fan System

Simulation-based validation is a vital approach for evaluating the performance of algorithms in a virtual setting by inducing faults and assessing their responses. This method proves essential for cost and time savings while addressing the challenges associated with acquiring real-world data. The hardware-in-the-loop simulation (HILS) technique has emerged as a valuable tool for creating a realistic and dependable simulation environment that interacts with real systems. This approach allows flexible modification and enhancement of state monitoring algorithms. In this study, we integrate a sensor system designed for remotely monitoring industrial scrubber fan systems with an actual scrubber fan setup. The monitoring algorithm undergoes testing using the HILS technique, employing a virtual fault injection system.
