Abstract
A control system () for controlling velocity and attitude of a dynamic system () includes a velocity controller configured to receive a desired velocity command and output a velocity error in the form of Euler angle commands to an attitude controller system. The attitude controller system includes a converter () configured to receive the Euler angle commands and output a desired quaternion based on the Euler angle commands. The attitude controller system further includes an attitude error generator () configured to receive the desired quaternion and an estimated quaternion indicative of an estimated velocity and attitude of the dynamic system () and to output attitude errors associated with the dynamic system (). The attitude controller system also includes an attitude controller () configured to receive the attitude errors and to output error commands to the dynamic system () based on the attitude errors.
