Advanced torque control of permanent magnet synchronous motor using finite element analysis based motor model with a real-time simulator

This study proposes advanced torque control of permanent magnet synchronous motors (PMSMs) using a finite element analysis (FEA) based motor model with a real-time simulator. This model can simulate the behavior of an actual motor including nonlinear characteristics such as spatial harmonics and magnet saturations. Therefore, model-based control with an FEA based motor model is advantageous for motor control. This study aims to achieve advanced motor control and drive techniques. In this study, high performance torque control techniques for PMSMs are proposed. The proposed torque control is developed based on direct torque control with torque prediction. This method can achieve fast response and smooth torque production. Its effectiveness is verified through simulations and experiments.
