6.5 MM of Double Fed Induction Machine (DFIM)
The mathematical model of DFIM can be derived as differential equations of five state variables. In addition to the rotor speed ωr, stator flux ψs and rotor current ir vectors are selected to represent the machine in [25,26]
For stationary reference, frame ωa is zero. For the machine working as generator, the speed ωr is an input to the model.
The multiscalar variables for DFIM can be selected as stators flux and rotor current, represented as [25,26]
where are the stator ...
