摘　　要：介绍了一种小型轻质化高动态伺服机构,针对航天飞行器小型化和高工作性能的要求,对伺服机构进行了小型化、轻质化计,采用永磁同步电机与传动机构平行式布局方案和壳体精细化的减重槽设计,以降低结构质量;通过侧壁安装的方式和混装电连接器等外部接口优化设计,降低了伺服机构的外形尺寸;采用位置-速度-电流环的三环控制与限波补偿控制策略相结合的控制方式,在实现伺服机构高动态响应的同时保证稳定性。通过理论分析和试验验证,该伺服机构方案设计合理、可行,满足安装空间和外形尺寸要求的同时,实现了高动态响应。A miniaturized lightweight high dynamic servo mechanism is introduced.According to the requirements of miniaturization and high performance of spacecraft,the servo mechanism is miniaturized and lightweight.In order to reduce the weight of the structure,the parallel layout of permanent magnet synchronous motor and transmission mechanism is adopted,and the refined weight reduction groove is designed.To reduce the dimension,the side wall installation and hybrid electrical connector is optimized.To realize the high dynamic response and ensure the stability of the servo mechanism,the position-speed-current loop three-loop control combined with the limit wave compensation control strategy is adopted.The theoretical analysis and experimental results show that the design is reasonable and feasible,having small volume and high dynamic response to meet the requirements.
