This paper studies the problem of observer-based control of space vehicles with fuel slosh dynamics in a zero gravity environment. Multi-mass-spring models are considered for the characterization of the most prominent sloshing modes. The control objective is to control the translational velocity vector and the attitude of the spacecraft, while attenuating the sloshing modes. A full-state feedback...
This paper studies the thrust vector control problem for an upper-stage rocket with fuel slosh dynamics. The control inputs are the gimbal deflection angle of a main engine and a pitching moment about the center of mass of the spacecraft. It is assumed that the rocket acceleration due to the main engine thrust is large enough so that surface tension forces do not significantly affect the propellant...
This paper studies the point-to-point liquid container transfer control problem for a PPR robot. A multi-mass-spring model is considered for the characterization of the most prominent liquid sloshing modes. The control inputs are two forces and a torque applied to the prismatic joints and the revolute joint, respectively. The control objective is to control the robot end-effector movement while suppressing...
