Time-varying Exponential Stabilization of the Attitude of a Rigid Spacecraft with Two Controls Time-varying Exponential Stabilization of the Attitude of a Rigid Spacecraft with Two Controls
Rigid body models with two controls cannot be locally asymptotically stabilized by continuous feedbacks which are functions of the state only. However, this impossibility does no longer hold when the feedback is also a function of time, and explicit smooth time-varying feedbacks which locally asymptotically stabilize the attitude of a rigid spacecraft have previously been proposed by the author...
متن کاملQuaternion-based Finite-time Sliding Mode Controller Design for Attitude Tracking of a Rigid Spacecraft during High-thrust Orbital Maneuver in the Presence of Disturbance Torques
In this paper, a quaternion-based finite-time sliding mode attitude controller is designed for a spacecraft performing high-thrust orbital maneuvers, with cold gas thrusters as its actuators. The proposed controller results are compared with those of a quaternion feedback controller developed for the linearized spacecraft dynamics, in terms of settling time, steady-state error, number of thrust...
متن کاملSliding Mode Control for Attitude Tracking of Thruster-Controlled Spacecraft
Nonlinear pulse width modulation (PWM) controlled system is considered to achieve control performance of thrustercontrolled spacecraft. The actual PWM controlled motions occur, very closely, around the average model trajectory. Furthermore nonlinear PWM controller design can be directly applied to thruster controlled spacecraft to determine thruster on-time. Sliding mode control for attitude tr...
متن کاملAdaptive Backstepping Sliding Mode Control of Spacecraft Attitude Tracking
This paper investigates the attitude tracking problem for rigid spacecraft. An adaptive backstepping sliding mode control law is proposed to solve this problem in the presence of inertia uncertainties and external disturbances. The control scheme is developed by combining sliding mode control with adaptive backstepping technique to achieve fast and accurate tracking responses. The proposed cont...
متن کاملTime-varying Feedback Stabilization of the Attitude of a Rigid Spacecraft with two controls
Rigid body models with two controls cannot be locally asymptotically stabilized by continuous state feedbacks. Existence of a locally stabilizing smooth time-varying feedback has however been proved. Here, such a feedback is ezplicitely derived. 1 Introduction The attitude control of a rigid spacecraft operating in degraded mode, i.e with only one or two controls, has already been much studied ...
