Özet

Reaction wheels, magnetic torque rods, momentum wheels and control moment gyroscopes (CMGs) are the most common actuators used in attitude control. However, they use rotor and/or gimbal mechanisms susceptible to failure. An alternative solution may be vibrating mass actuators. Previous research by Reiter et al. and Chang et al. showed the possibility of obtaining a net output torque from vibrating actuators. To build upon this, current research aims to expand the vibratory actuators to different and more complex architectures such as double axis CMGs. Additionally simulation models will be built to investigate their functioning in satellite attitude pointing scenarios.
