The errors between estimated torque/flux and their respective reference values are mapped to digital command states. These states, combined with the spatial sector location of the stator flux vector, index a predefined lookup switching table. This table immediately selects the optimal inverter voltage vector ( V⃗1modified cap V with right arrow above sub 1 V⃗6modified cap V with right arrow above sub 6

SVM increases the maximum output fundamental voltage by approximately 15.5% compared to standard sinusoidal pulse-width modulation.

"Electrical Machines and Drives: A Space-Vector Theory Approach" by Peter Vas is a comprehensive 1992 monograph in the Oxford University Press series that provides a unified mathematical framework for analyzing steady-state and transient machine operations. The work covers space-vector theory for induction and synchronous machines, incorporating non-linear magnetic saturation and variable-speed drive analysis suitable for simulation and design.
