SABER-Based Modeling and Simulation of Induction Motor Drive System for EVs

Abstract. Simulation tools are of great assistance to engineers and researchers to reduce productdevelopment cycle time, improve the quality of the design, and simplify the analysis without costly and timeconsuming experiments. In this paper, a model of Electric Vehicles (EVs) propulsion system has been constructed with the simulation platform SABER. It was chosen because of the robust modeling engine, the ease of integrating mechanical components, and the large library of existing models for a wide range of electrical components. This paper discusses the validity of the system model by creating module boxes for not only the electrical systems, but also the mechanical system of the vehicles. These modules include induction motors, voltage source inverters, vector control algorithm, and vehicle load torque module. The correctness and validity of this system are demonstrated by the simulation results of vector controlled induction motors and typical drive cycle condition. System-level analysis can be used to assess long-term behavior of EVs, and dynamic models are helpful to provide in-depth information about the short-term behavior of sublevel components. The model allows for real time evaluation of a wide range of parameters in vehicle operation as pure EVs.
