  1. Obtain Speed feedback, compare with reference speed ωr*.
  2. Process Speed error through a speed PI controller to obtain reference torque value Te*.
  3. Feedback stator voltage and currents in stationary reference frame.
  4. Estimate Stator flux phasor magnitude (Ψs or λs) and angle (θs).
  5. Estimate Electromagnetic Torque (Te)
  6. Obtain error in stator flux, pass it through two level hysteresis controller to get dΨs.
  7. Obtain error in electromagnetic torque, pass it through three level hysteresis controller to get dTe.
  8. Obtain sector number (N) based on θs
  9. Pass the flux, torque controller output and sector information (dΨs, dTe, N) through vector selection table to obtain the suitable switching signal for the VSI (Sa, Sb, Sc).
