-axis with the rotor flux (or stator flux), the torque and flux can be controlled independently, mimicking the performance of a separately excited DC motor [3]. Control: Controls the flux magnitude. Control: Controls the electromagnetic torque. 4. Space Vector Pulse Width Modulation (SVPWM)

a comprehensive technical monograph that provides a unified mathematical and physical analysis of AC and DC machines using space-vector theory . Published by Clarendon Press (Oxford University Press)

For a symmetric three-phase system, the instantaneous phase variables (currents, voltages, or flux linkages) can be represented as . The complex space vector

Sensorless Control and Observers

The author (typically associated with the deep academic work from the 1990s/2000s on this topic) builds the entire theory from the ground up using vector notation. You will start with the general theory of electrical machines, then systematically derive the transformations (Clarke, Park) that make control possible. -axis with the rotor flux (or stator flux),
