This paper examines various control strategies for a marine gyrostabilizer system, including
passive and derivative-based control methods and proposes two new marine gyrostabilizer …

In this study, a neuro-fuzzy controller (NFC) was developed for spacecraft attitude control to
mitigate large computational load of the state-dependent Riccati equation (SDRE) controller …

SINGULARITY avoidance in variable-speed control moment gyroscope (VSCMG) systems
can require significant computation to determine null motion steering commands. This paper …

In this paper, dual control moment gyroscopic actuators (CMG) were formed in a scissored-
pair configuration to maximize the induced torque in the desired direction. A robust …

The stability and singularity problem of agile small satellite (ASS) with actuator failure is
discussed in this paper. Firstly, the three-axis stabilized controller of an ASS is designed …

Various embodiments of the present invention include an attitude control system for use with
small satellites. According to various embodiments, the system allows rapid retargeting (eg …

Abstract A Variable Speed Control Moment Gyro (VSCMG) is a recently introduced actuator
for spacecraft attitude control. As its name implies, a VSCMG is essentially a single-gimbal …

Advanced performances in nanospacecraft are typically associated with high onboard
