Fault Diagnosis Of Lubrication Decay In Reaction Wheels Using Temperature Estimation And Forecasting Via Enhanced Adaptive Particle Filter, Madhi Aldadi
Electronic Theses and Dissertations
Reaction wheel (RW), the most common Attitude Control Systems (ACS) in satellites, are highly prone to failure. A satellite needs to be oriented in a particular direction to maneuver and accomplish its mission goals; losing the RW can lead to a complete or partial mission failure. Therefore, estimating the remaining useful life (RUL) in long and short spans can be extremely valuable. The short-period prediction allows the satellite's operator to manage and prioritize mission tasks based on the RUL and increases the chances of a total mission failure becoming a partial one. Studies show that lack of proper bearing lubrication …

A Data-Driven Approach Using Long-Short Term Memory For Fault Prognosis And Remaining Useful Life Estimation Of Satellite Reaction Wheel, Md Sirajul Islam
Electronic Theses and Dissertations
Artificial satellites are objects or a body that are stationed in the orbit of another object. The purpose of artificial satellites includes monitoring, information transfer, studying a different planet, space exploration, and fulfilling many other modern-day needs. For the increased demand, the number of artificial satellites revolving around the earth is also increasing. Due to cost efficiency, bulk manufacturing capability, and ease to launch in the orbits, small satellites are the topic of interest. Reaction wheels are widely used in the attitude control system of small satellites. Unfortunately, reaction wheels failure restricts the efficacy of a satellite, and it is …
