Abstract:
This paper introduces the stator flux vector control
method for three-phase asynchronous motor under
conditions of magnetic saturation, this controller
requires parameters of stator voltages, stator currents,
and stator resistance, flux is estimated from the
measured currents, a combination of 5
th
cascade
inverter and POD carrier modulation algorithm are
applied to increase the stability of the controller.
The simulation and experiment on matlab/simulink
for 1-hp, 150-rad/s squirrel-cage rotor motor, using
DSP 320F28335, the results show the measured speed
following the set value when changing from the
lowest 3 rad/s up to a peak of 150 rad/s, the system
remains stable when the stator and rotor resistances
change up to 2 times their initial values in the
presence of noise
