Adaptive Control for Spacecraft with Flexible Appendages with Unknown Parameters
<p>Flexible spacecraft pose several challenges in control design due to the uncertain dynamical model and the underactuated nature of these systems. Adaptive and robust controllers are the common choice for these systems to either meet operational requirements like attitude pointing or to suppress …

A Novel Magnetorheological Fluid Damper for a Small Spacecraft with Flexible Appendages
… electrical power may be the adoption of larger, flexible solar arrays. However, spacecraft with flexible appendages have historically presented attitude control challenges relating to platform stability given the dynamic response of the flexible components to applied torques. These challenges may …

Proportional-Derivative-Acceleration Feedback Controller Design for Single Axis Attitude Control of Rigid Spacecraft with Flexible Appendages
… performance of single axis attitude control of flexible appendages attached to a rigid spacecraft. Conventionally, PID with position feedback was used to control single axis attitude manoeuvre of flexible appendages on a spacecraft but designing a PID to control a higher order system is a …

Nonlinear attitude control of spacecraft with strain-actuated solar arrays
… of freedom cylinder (rigid body rotation) with flexible appendages (infinite-dimensional system). The equations of motion that describe system evolution are derived using the extend generalizations of the Lagrangian for infinite dimension systems. Precision attitude control is achieved by …

Dynamics and control of spacecraft with retargeting flexible antennas
… rigid platform and a given number of retargeting flexible antennas. The mission consists of maneuvering the antennas so as to coincide with preselected lines of sight while stabilizing the platform in an inertial space and suppressing the elastic vibration of the antennas. The dissertation …
