Co-simulation perspective on evaluating the simulation with the engine test bench in the loop

Abstract

This article shows how a hardware in the loop (HIL) simulation can be formulated in such a way that the quality of the simulation can be assessed by evaluating the total energy residual (TER). The validity of this approach was checked with the standard co-simulation to show that TER can be used to compare non-iterative Jacobi and Gauss-Seidel co-simulation masters. The given example with the known global error shows that the value of TER can correctly determine which of the co-simulation masters is better. In the experimental part of the article, the example of a HIL simulation with an engine test bench in the loop is presented. The experiments show that such a quality assessment approach can be used to determine the speed controller parameters for the engine test bench.
