So it has been widely applied in power generation and drive systems over a wide range of speeds. In this paper, the basic characteristics of HESM are discussed, and several kinds of the typical structure and operation principles of HESM are analyzed. A novel topology of HESM is proposed. The mathematic model of HESM is derived. Based on stage control, 0 the control system is established. Several control strategies are analyzed in both low and high speed regions. Based on the analysis of the problem existing in the control technology of HESM, a novel efficiency optimization control strategy of
