Abstract: This paper presents a dual-stage control system design method for flexible spacecraft attitude tracking control and active vibration suppression by an embedded smart material as sensors/actuators. ...

Abstract: Semiglobally input-to-state stable (ISS) control law is derived for flexible spacecraft attitude maneuvers in the presence of parameter uncertainties, external disturbances, and actuator fault. As a stepping stone, a ...

Abstract: In this paper, finite-time output feedback coordinated attitude control for spacecraft formation subject to input saturation is investigated. More specifically, a finite-time observer is first designed to remove the ...

Abstract: A hybrid control scheme for vibration reduction of flexible spacecraft during rotational maneuvers is investigated by using variable structure output feedback control (VSOFC) for attitude control ...

Abstract: This paper investigates the design of spacecraft attitude stabilization controllers that are robust against actuator faults and external disturbances. A nominal controller is developed initially, ...

Abstract: This paper presents a dual-stage control system design method for the attitude tracking control and vibration stabilization of a spacecraft with flexible appendages embedded with piezoceramics as sensor and actuator. In ...

Abstract: A velocity-free attitude fault tolerant control scheme is presented to stabilize spacecraft attitude. A terminal sliding-mode observer is developed to reconstruct system states. With the reconstructed attitude and angular ...
