Continuous quaternion based almost global attitude tracking with LMI multi-objective tuning
Abstract
This paper considers the attitude control problem of a generic rotating 3 degrees of freedom fully actuated rigid object. The specific studied problem is the deviation control of this object around a theoretically feasible attitude trajectory. The rotation motion has an intrinsic non linear behaviour (trigonometric, 2π-periodicity) that may lead to build non linear and hybrid controllers. This paper considers the opportunity to use the quaternion framework to build a continuous non linear controller that reaches an almost global asymptotical stability.
