Variable structure control and active vibration suppression of flexible spacecraft during attitude maneuver
Qinglei Hu,Guangfu Ma +1 more
TL;DR: In this paper, a new approach to vibration reduction of flexible spacecraft during attitude maneuver by using the theory of variable structure control (VSC) to design switching logic for thruster firing and lead zirconate titanate (PZT) as sensor and actuator for active vibration suppression is presented.

Satellite attitude control by quaternion-based backstepping
TL;DR: In this article, the attitude control of a microsatellite by integrator backstepping based on quaternion feedback is presented, and the controller is shown to make the closed loop equilibrium points asymptotic stable in the sense of Lyapunov.

Spacecraft Vibration Reduction Using Pulse-Width Pulse-Frequency Modulated Input Shaper*
TL;DR: In this paper, the authors presented the first study of Pulse-Width PulseFrequency (PWPF) modulated thruster control using command input shaping, which takes full advantage of the pseudolinear property of a PWPF modulator and integrates it with a command shaper to minimize the vibration induced by on-off thruster firing.

Pulse Modulated Control Synthesis for a Flexible Spacecraft
TL;DR: In this article, the authors employed the describing function method for the nonlinear control analysis and design of a flexible spacecraft equipped with pulse modulated reaction jets, which provided a means of characterizing the pulse modulator in terms of its gain and phase for structural mode limit cycle analysis.
