Control and Characteristic Map Generation of Permanent Magnet Synchronous Machines and Induction Machines with Squirrel Cage

Due to different requirements for simulation during the design process of an electric drive system, investigations were carried out to supply models of different stages with consistent sets of parameters. Therefore physical models of the Modelica Standard Library (MSL) were equipped with state-of-the-art control strategies to operate in realistic conditions. These include field-oriented algorithms for permanent magnet and induction machines including field-weakening, current and voltage limitations as well as maximum torque per ampere blocks. In the full paper it is presented how the losses computed by the physical model are transfered to the characteristic maps. Those losses are stored in tables to speed up simulation in cases where dynamics are of minor interest. These table-based models can then be used for energetic, thermal and life-time analysis with a consistent set of parameters generated from their physical counterparts. The physical models from which the map-based models were created can be applied when dynamics or other detailed effects in the machine or the controller are of interest.
