“…In [18], the machine flux-weakening implement is realized by imposing on the stator armature winding and rotor excitation winding currents, which means stator armature current control with a proper linearization voltage loop and rotor excitation current control with the purpose of enlarging operation speed by feed-forward method are designed, respectively. In [19], a local minimum function control method for the instantaneous value of reverse energy based on the dynamic characteristics of the HESM at twice the nominal speed is presented. This method does not need to modify the controller parameters every time, and its validation is obtained in four different structures of HESMs.…”

With combining the advantages of the hybrid excited machine and field modulation machine, hybrid excitation field modulation machine (HEFMM) exhibits obvious merits of controllable flux operation and independent flux distribution paths, which is one promising candidate for direct drive application fields. As one newly branch of hybrid excitation synchronous machine (HESM), HEFMM control method can be executed based on the characteristics of the machine operating in different speed regions. When it operates in the low-speed constant power region, the minimum copper loss method is used to optimize the d-axis, q-axis, and excitation current values. When it operates in the high-speed constant power characteristic region, flux weakening fuzzy control strategy combined with particle swarm optimization algorithm for HEFMM was presented. The correctness and effectiveness of the proposed flux weakening fuzzy control strategy were verified by the simulation data and experimental results, which demonstrated that the this current optimization method based on PSO algorithm can effectively reduce the total copper loss of the machine by 22.8%, the range of speed regulation with higher efficiency are obtained.
