大功率开绕组内置式永磁伺服系统驱动控制策略研究

In the field of aerospace, conventional hydraulic actuator is being gradually replaced by electro-mechanical actuator (EMA), which is based on the technology of power-by-wire , and has the merits of simple structure, good dynamic performance, easy to use and maintain. To meet the requirements of “high power/torque density, high reliability, high precision and high dynamic performance” for EMA, an open-winding interior permanent magnet servo motor (OW-IPMSM) with common DC bus and its drive system are proposed in this project. Basic operation principle and design method of the motor with the open-winding typology will be studied. Moreover, the motor drive mode and fault-tolerant control method will be investigated to improve the power/torque density and reliability. The design method of active disturbance rejection control (ADRC) controller considering the delay caused by digital control system and the filter in feedback will be researched. Meanwhile, the parameter identification methods and the design methods of adaptive ADRC controller will also be studied so as to improve the static and dynamic performance of the control system. The project will explore the application of parameter identification theory and ADRC theory in motor control, and will also provide theoretical basis and technical support for the application of OW-IPMSM in high power EMA.
