| Summary: | This paper presents a methodology for systematically scaling vehicle powertrain and other models and an approach for using model parameters and scaling variables to perform controller design. The parameter scaling method allows for high degrees of scaling while maintaining the target performance metrics, such as vehicle speed tracking, with minimal changes to the model code by the researcher. A comparison of proportional-integral, Youla parameterization, <inline-formula><math display="inline"><semantics><msub><mtext mathvariant="normal">H</mtext><mo>∞</mo></msub></semantics></math></inline-formula>, and hybrid Youla-<inline-formula><math display="inline"><semantics><msub><mi mathvariant="normal">H</mi><mo>∞</mo></msub></semantics></math></inline-formula> controllers is provided, along with the respective methods for maintaining controller performance metrics across degrees of model scaling factors. The application of the scaling and various control design methods to an existing model of a hydrogen fuel cell and a battery electric vehicle powertrain allows for the development of a representative scale model to be compared with experimental data generated by an actual scale vehicle. The comparison between scaled simulation and experimental data will eventually be used to inform the expected performance of the full-size electric vehicle based on full-size simulation results. |
