Starting Control of Three-stage Synchronous Motor based on Improved Current-coordinated Vector Control

Abstract

Compared with traditional aircraft technology, more electric/all electric aircraft has larger capacity, simplified structure, higher power density and equipment utilization. At present, the most widely used three-stage synchronous motor starter/generator system in more electric aircraft has also become an important research content. An improved current-coordinated vector control method based on model predictive control is proposed for starting control of three-stage synchronous motor. This method does not require complex flux observer, makes full use of the excitation current of three-stage synchronous motor. The simulation results show that the method improves the dynamic response performance and parameter robustness of the system, which is beneficial to practical engineering application. (Abstract)
