Abstract

Fuel slosh dynamics can disturb attitude of spacecraft which has a partially filled container, in orbital maneuvering. So, it is necessary to control this harmful phenomenon. This paper models coupled dynamics of fuel sloshing and attitude of the spacecraft by two-pendulum model, and designs a fuzzy controller to control sloshing and attitude dynamics of the vehicle. Also, effectiveness of this controller is illustrated by conducted simulation.

航天器晃动动力学的二维建模与模糊控制
在轨道机动过程中,燃料晃动会对带有部分填充容器的航天器的姿态产生干扰。因此,有必要控制这种有害现象。本文采用双摆模型建立了航天器燃料晃动与姿态耦合动力学模型,并设计了模糊控制器对飞行器晃动和姿态动力学进行控制。并通过仿真验证了该控制器的有效性。
