Control moment gyroscope singularity avoidance for agile spacecraft
Abstract
After the first artificial Earth satellite launched into space on 4 October 1957 by the lead of the Soviet rocket engineer Sergei Korolev, the development and launch of a huge amount of satellites has followed. With the development of a standardized model for manufacturing small satellites in 1999, CubeSats have become a widespread and significant trend for performing a variety of tasks with low fabrication cost. In a data-driven era, the more data satellites gather in a given time, the more effective they are and the demand for speed is translated into demand for developing a system capable of providing the desired agility.Control Moment Gyroscopes (CMGs) have been known as high torque actuators because they exploit the torque amplification effect while following low mass, volume and power restrictions. Their major and inherit problem is this of singularities. This dissertation takes into consideration the problem of singularities proposing novel methods for global steering the 4-CMG ...
