摘要
采用控制力矩陀螺实现的姿态机动,无需消耗燃料,被称为零燃料姿态机动。为研究零燃料姿态机动,设计并实现了空间站零燃料姿态机动数值仿真系统,考虑了陀螺框架角速度限制等工程约束,引入了姿态敏感器、陀螺框架角等误差因素;对规划的姿态机动路径进行仿真,通过验证陀螺是否发生饱和,判断机动路径的可行性。数值仿真结果表明,通过控制器设计,数值仿真系统满足姿态控制精度和稳定性的要求,可作为空间站零燃料大角度姿态机动路径规划结果的仿真验证平台。
Attitude maneuver,only with control moment gyros as actuator,is called Zero-propellant maneuver.A Zero-propellant attitude maneuver numerical simulation system for space station was designed and implemented,considering not only the primary project restraint such as frame-angle velocity limitation,but also the influence of frame-angle errors,disturbing torque and sensor errors. The planning path was verified,and the feasibility was decided according to whether CMG is saturated or not. The result of numerical simulation shows that the simulation can meet the requirements of precision and stability with the design of controller,and the simulation system is a dependable platform to verify the planning path of large-angle attitude maneuver for space station.
