Hardware-in-the-Loop Simulation of a Dynamic Process by Compensation of the Transfer System

Abstract:

Hardware-in-the-loop simulation is widely used for component and controller testing, for which purpose a transfer system typically comprising sensors and mechanical actuators is used to link the software and hardware subsystems. The effect of coupling the transfer system to the test system can be ignored for a steady or slowly changing process, but not for a highly dynamic process. In this paper, we propose a feedforward methodology for compensating for the coupling effect without increasing the noise bandwidth designed for a steady or slowly changing process when simulating a dynamic process. We also present an analysis of the results of the experiments in automotive engineering used to verify the proposed methodology.
