The dual-electrical-port dual-mechanical-port(DEP-DMP) machine is a new type of multi-functional integrated machine, which contains at least two rotors and two sets of windings. DEPDMP machine is used to realize power transmission and distribution between multiple mechanicalports and electrical-ports, and decouple control of torques and speeds of two mechanical-ports. It has the advantages of high compactness, high integration and multi-port cooperative operation, and has good application potential in the fields of wind power generation, new energy vehicles, and hybrid ships. This paper firstly introduces the structure and operation principle of the DEP-DMP machine,and briefly analyzes the way to achieve multi-function. The research and innovation of the brushed and brushless DEP-DMP machines on the topology structure are classified, and the advantages and disadvantages of each are summarized. Then, the DEP-DMP machine control methods are introduced from the three aspects of decoupling control, capacity management and dynamic and steady-state optimization. Finally, the research direction and development trend of the DEP-DMP machines are prospected.
