Tiivistelmä
This thesis focuses on the modeling of model order reduction (MOR), and control techniques integration of Interior Permanent Magnet Synchronous Machines (IPMSMs) using Finite Element Analysis (FEA) within the ANSYS Electronics Desktop environment. A highly detailed parametric electromagnetic model of the IPMSM was developed using ANSYS Maxwell 2D and RMxprt, capturing complex physical behaviors such as magnetic saturation, magnetic flux distribution, load torque ripple, static currents, inductance and currents.
For addressing the computational limitations of high-order finite element models in control development, a reduced-order model was constructed through dynamic co-simulation using the Sim Explorer module. This approach enables the integration with real-time-compatible block that maints the FEM model accuacy with significant lower computational speed.
The resulting reduced-order model was evaluated in the ANSYS Sim explorer environment for making sure accuracy in key electromagnetic metrics. The workflow developed in this thesis supports a streamlined transition from electromagnetic design to control validation, without the need for third-party platforms.
