Multiphysics Modeling and Optimization of a Compact Actuation System

Abstract

This paper describes a methodology for the optimization of complex actuation systems, using analog simulations and an evolutionary algorithm. Our proposal consists on the development of an automated design framework that helps the designer to quickly complete a pre-sizing step while ensuring that multi-domain requirements are met within short development times typical of automotive industry. Multiphysics constraints can be handled, allowing the sizing of a complete automotive mechatronic system. The effectiveness of the methodology is demonstrated in the case of an exhaust gas recirculation (EGR) valve. Electrical, mechanical, thermal and magnetic requirements are met while a minimal volume is reached.

Optimal Design of PMSM Based on Automated Finite Element Analysis and Metamodeling

“…Optimization of multi-physics systems by simulation takes significant computing time for each simulation run, and its process depends on numerous runs, making it difficult and expensive [30]. However, using the automated DOE procedure suggested in this study can reduce design cost and time, so I think multi-physics analysis is possible in the near future.…”

A cycle-based formulation for the simulation of multi time-scale systems — Application to the modeling of the storage system of a fully electric ferry

“…This method can be replaced by a cycle-based formulation, by considering a first scale with the PWM cycle (M ), a second scale with a sine wave period (S) which can then be extrapolated over few hours (H). In (Robert et al, 2017), the authors consider an exhaust gas recirculation valve, which takes into account the electrical, mechanical, thermal and magnetic domains. The simulation is achieved with an average model for the power converter and with a relaxation method for the thermal behavior.…”
