Claim 15:
16. A method for controlling a rotating electromechanical actuator with two three-phase stator windings, comprising:
simultaneously driving three phases of each of first and second windings of a motor using output signals of at least one voltage source inverter;
detecting a fault that is located within a first phase of the first winding;
driving only non-faulted second and third phases of the first winding and the three phases of the second winding using the output signals of the at least one voltage source invertor, wherein the driving includes:
implementing interactive control loops for monitoring and adjusting the output signals to drive non-faulted phases of the first and second windings, the interactive control loops including a current loop configured to provide input to at least a flux weakening loop, the current loop further receiving reference currents, in the form of reference sums and differences, from the flux-weakening loop; and
adjusting the output signals of the at least one voltage source invertor to the second and third phases of the first winding and the three phases of the second winding based on interactive control loops.
