Multi-Domain Modeling and Simulation of Mechatronic Systems

Automotive applications require complex systems with strong interaction between electrical and mechanical modes of operation. To achieve fast to market products and reduce development costs, math modeling is essential to analyze these complex mechatronic systems and accurately characterize their behavior. One of the tools widely employed by GM to address this need is Sabera®. While Sabera® is well developed in electrical and mechanical domains, it is difficult to accurately model the magnetic behavior. To alleviate this problem, the magnetic circuit is characterized by the finite element analysis program, Maxwell®, and then integrated with Saber®. This paper discusses the development of models using this process with a transmission application.
