BILEVEL OPTIMIZATION FOR FAST CONTROL MOMENT GYRO MANEUVERS
Agility is at the forefront of considerations on control moment gyro-equipped spacecraft. Common approaches to allocating control moment gyro gimbal rates for commanded body torques often sacrifice torque authority for straightforward, analytical methods that can be readily implemented in flight …

Mixed Control Moment Gyro and Momentum Wheel Attitude Control Strategies
Attitude control laws that use control moment gyros (CMGs) and momentum wheels are derived with nonlinear techniques. The control laws command the CMGs to provide rapid angular acceleration and the momentum wheels to reject tracking and initial condition errors. Numerical simulations of derived …

Design and Development of a Self-Balancing Bicycle Using Control Moment Gyro
This thesis reports the use of gyroscopic stabilization to balance kid-size bicycle. A self-balancing bicycle is a non-linear unstable system similar to that of an inverted pendulum. Experimental results show the robustness and efficiency of a proportional plus derivative (PD) controller balancing …

Design and integration of a three degrees-of freedom robotic vehicle with control moment gyro for the Autonomous Multiagent Physically Interacting Spacecraft (AMPHIS) testbed
… to simulate autonomous guidance, navigation and control (GNC) for spacecraft proximity operations and assembly within the framework of the Autonomous Multi-Agent Physically Interacting Spacecraft project. The new spacecraft simulator includes several key enhancements over the previous Autonomous …

Spacecraft nonlinear attitude control with bounded control input
The research in this thesis deals with nonlinear control of spacecraft attitude stabilization and tracking manoeuvres and addresses the issue of control toque saturation on a priori basis. The cascaded structure of spacecraft attitude kinematics and dynamics makes the method of integrator …
