Optimization of the control of a doubly fed induction machine

This paper focuses on finding an optimal control for a doubly fed induction machine (DFIM) in motor mode. Our purpose is not to improve the quality of the DFIM functioning but to find a method to improve it. Thus we will start with a fixed system made by a DFIM and two ideal 3 phases voltage inverter with an open loop static V/f control. A method will demonstrate its efficiency to improve that control for the copper loss. This method is based on direct shooting techniques associated with a MATLAB optimization solver:fmincon
