Modeling of hybrid excitation synchronous machines is a crucial step for the determination of control laws. The combination of analytical and numerical models is very useful for high model reliability without being penalized on the computation time. With this method, a field-weakening control strategy is used in this paper. The excitation flux is controled beyond the base speed through torque angle and excitation current while maximizing total efficiency of the machine.
