Abstract
The application of doubly salient electromagnetic machine(DSEM) to more electric aircraft starter/generator system has broad prospects. And the more electric aircraft are extremely demanding on operational reliability, which is mainly determined by the operating stability of the starter/generator system. Therefore, DSEM's fault-tolerant control technology plays a significant role in improving the operational reliability for more electric aircraft. At present, the researches on fault-tolerant control of DSEM mostly focus on the fault-tolerant design of body structure. There are few studies on fault-tolerant operation control under excitation fault. In this paper, a three-phase six-state control method based on the full-bridge converter is proposed to enable the DSEM in generating operation to continue generating electricity without field current. And the experiments are carried out to verify the correctness of the proposed control strategy.
