ROBUST FEEDBACK LINEARIZATION AND GH CONTROLLER FOR A QUADROTOR UNMANNED AERIAL VEHICLE

Abdellah Mokhtari - Abdelaziz Benallegue - Boubaker Daachi

   In this paper, a mixed robust feedback linearization with linear GH controller is applied to a nonlinear quadrotor unmanned aerial vehicle. An actuator saturation and constrain on state space output are introduced to analyse the worst case of control law design.The results show that the overall system becomes robust when weighting functions are chosen judiciously. Performance issues of the controller are illustrated in a simulation study that takes into account parameter uncertainties and external disturbances as well as measurement noise.

Keywords: UAV, GH, sensitivity, robust linearization
