This paper describes the indirect field orientated control method in a high power application. Due to the low switching frequencies, the stator currents have to be controlled through the stator voltages to take into account the stator dynamic behaviour. To detect accurately the rotor flux vector, an estimator is used associated with a parameter compensation scheme. An experimental drive is being studied to validate the proposed schemes.
