Abstract: To better adapt to changes in the demand for the output characteristics of the servo system under the multi-extreme conditions of the spacecraft and requirements for high reliability applications, a novel high reliability motor system is presented, including the reconfiguration controller, adjustable drive topology and fault-tolerant motor. According to needs of the spacecraft, the connection mode of the driver and the motor winding is reconfigured online to transform the structure and to alter parameters of the motor system, and then the output performance of the motor system is reconfigured simultaneously to realize the goal of achieving the best performance required for aerospace missions under each working condition. When there is a fault in the driver or windings, the structure of the whole motor system will also be reconfigured to isolate the fault and perform fault-tolerant control, so that the remaining normal parts can still output the required torque to achieve remedy operation of the motor system and ensure high reliability applications of the system.

Key words: reconfiguration, motor system, system structure transformation, fault-tolerant control, drive topology
