论述了载人机动装置（MMU）在载人航天中的作用，介绍了MMU控制系统的配置，MMU姿控发动机与轨迹控制发动机的协调控制，MMU的姿态测量以及姿态控制逻辑，分析了MMU姿态控制与轨迹控制的相互影响，最后给出MMU舱外活动的姿态控制以及姿态和轨迹连锁控制的数学仿真结果。
The role of manned mobile unit (MMU) in manned space flight is discussed. The configuration of MMU control system, the coordinated control of MMU attitude control engine and trajectory control engine, the attitude measurement of MMU and the attitude control logic are introduced. The MMU attitude The interaction between control and trajectory control is given. Finally, the attitude control of attitude control and trajectory control of MMU are given.
