高可靠电机系统主动变结构与容错控制技术

为了更好地、更高性能地适应航天器多极端工况对伺服系统输出特性的需求变化以及高可靠应用需求，提出了一种新型高可靠电机系统，其主要包括变结构控制器、可变结构驱动拓扑和变结构容错电机。根据系统所需，通过在线变换驱动器与电机绕组的连接方式，重构电机系统结构和参数，进而改变电机系统的输出性能，最终实现每个工况下均能达到航天任务所需性能最优的目的；在驱动器或者电机绕组发生故障时，亦可通过电机系统结构变换，将故障进行隔离并进行容错控制，让剩余的正常部分还能输出所需的扭矩，实现电机系统的带故障运行，保证系统具有故障-工作的高可靠性能力。

Active reconfigurable and fault-tolerant control technology for high reliability motor system

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.
