Measurement-parameterized synchronous machine model with spatial-harmonics

This paper presents an advanced measurement-parameterized synchronous machine model. The model takes into account saturation, cross coupling and spatial harmonics. The measurement setup, measurement procedure and needed mathematics are derived. The flexible model structure allows to take into account permanent magnet and synchronous reluctance motors. The machine data is also used to determine nonlinear control tables for accurate torque control. Finally, the extracted machine model and torque controller with its control tables and control parameters is evaluated.
