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 …

Stochastic electron trajectories and wave interaction in relativistic gyro-traveling wave amplifiers
Gyro-traveling-wave amplifiers (gyro-TWAs) are types of gyrodevices, which take advantage of the cyclotron maser instability to produce coherent electromagnetic (EM) radiation from electrons gyrating in an external magnetic field and interacting with fast traveling waves. For high power …

A numerical, time domain solution for the response of a Gimbal supported gyro
… solution for the response of a gimbal supported gyro to arbitrary forcing functions and base motion, and includes the normal parasitic effects of bearing friction, viscous pivot damping, and pivot spring constants. There are relatively few restrictions on gyro and gimbal structure geometry. …
