Field-oriented control requires knowledge of

  • A.the ambient temperature in which the machine is installed
  • B.the harmonic content of the supply feeding the drive
  • C.the position of the rotor flux
  • D.the mechanical load torque at every instant of operation

Answer: C

The transformation into flux and torque axes is meaningless without knowing where the flux is, and estimating it accurately at low speed is the hard part. Direct schemes measure it and indirect schemes compute it from the currents.
