英文摘要： In order to further improve and enhance the SRM operating performance and fault-tolerant performance, this project takes a new type of modular stator SRM with segmental rotors as the research object to study the key technologies of this machine. Hierarchical optimization design and magnetic network with 2D and 3D finite element method are combined to design and analysis of this machine. The mathematical model is proposed and the operating characteristics of this type of machine and machine topology, the internal laws of the winding arrangement and connections and electrical parameters is explored. Combined with new Boost drive circuit, high-performance direct instantaneous torque control strategy is studied to reduce the torque ripple. A 3D field-circuit coupling system-level model is created to analyze the faulty performance and transient fault process under different types of faults for the system. For different types of faults and system performance requirements, active fault tolerant control strategies are studied to improve the fault tolerance of this modular motor drive. Prototype is developed by selecting representative program. And the semi-physical simulation model and real-time motion control system platform is established to simulate and analyze the performances of different controlled object, which is used to verify the correctness of the theory and the control algorithm. Then the general design and control laws for the high-performance and fault tolerance modular stator SRM are summed up. The project will further expand the applications of the new structure SRM and lay the theoretical and technical basis for its application in the aerospace and electric vehicles.
