Impact of the motor magnetic model on direct flux vector control of interior PM motors [PDF]
The stator-field-oriented, direct-flux vector control has been proven to be effective in terms of linear torque control and model independent performance at limited voltage and current (i.e. in flux weakening) for AC drives of various types.
