Quaternion feedback attitude control system design based on weighted–L2–gain performance
The operation and accomplishment of a satellite's mission depend on its capacity to control its attitude. A rotation matrix parameterization, such as a (unit) quaternion, is frequently used to represent the attitude information needed for attitude ...

Matrix representation of quaternions
The authors establish that there are 48 distinct triples of real \(4\times 4\) signed permutation matrices \(H,K,L\), subject to the well known conditions \(HH=-I\), \(HJ=K\) etc., which together with the identity matrix \(I\) will serve as a basis in the regular representation of the real quaternions.
