A control strategy in variable speed for a special electrical machine.
Analytical calculation of currents which are able to keep a constant torque even in faults modes, whose parameters allow an easy control in variable speed.
Numerical optimization of currents parameters (in each mode) in order to reach the maximum torque values under current and voltage constraints.
Flux weakening operation in fault mode.
Experimental validation of open-circuited faults, with a fault-tolerant 5-phase PMSG associated to a 5-leg converter.
