基于Theta-D次优控制器设计的相对姿轨耦合控制
Relative Coupling Attitude and Position Control Based on Theta-D Suboptimal Control Design
摘要
Abstract
According to the on-orbit service spacecraft's features like quick maneuver and cooperative translation and attitude control, an optimal control scheme is proposed based on holonomic coupled translation and attitude model. The coupled nonlinear equation of 6 DOF relative motion including both rotation and translation is obtained . in which continuous eccentric thruster vector provides position control forces as well as attitude control torques. Linearization method of dynamic model and θ - D constructive optimal solution are employed to give numerical algorithm for optimal control problem of coupled translation and attitude motion which control service spacecraft position and attitude simultaneously and make it approach in a straightline to a disabled tumbling target. The proposed method is validated and numerical results demonstrat its efficiency on basis of required stability and performance, which do have some engineering sense for potential application.关键词
