Abstract
The inherent non-idealities, especially the time delay, in the interface of a PHIL simulation may lead to large simulation errors or even instabilities. Therefore, it is extremely important to have an effective way to evaluate the simulation accuracy in order to justify the reliability of a PHIL experiment. A generalized metric defining the error functions from two types of PHIL interface perturbations is proposed in this paper. Two simulation examples are performed to show the validity of the proposed method.
