Control Moment Gyros (CMGs) are commonly used as actuators of attitude control in
spacecraft. Micro-vibrations generated by CMGs will influence the performance of high …

The increased need in pointing performance for Earth observation and science Space
missions together with the use of lighter and flexible structures directly come with the need of …

The present study describes a method of using a nonlinear energy sink (NES) to realize
vibration reduction of the flywheel system, and integrates the NES with the flywheel support …

Reaction wheel assemblies (RWAs) are a source of disturbance in satellites, and they are
regarded as the largest jitter contributor in optical payloads. In order to ensure a stringent …
