...The state space model (14) does not imply an integral action on the error (1), furthermore, robust tracking control can be achieved by extending (14) and introducing an integral state vector XI ∈ R(3) with the following time derivative to force the error to converge to zero [15] [16]...

...Even though most of the related research work was only applied to the simulation level, some control approaches have been validated experimentally, such as LQ [1][4], backstepping [4], and sliding-mode control [4] methods for quadcopter hovering, although most of the validated methods are based on the PID framework [1][4][6]....

...Many variations of classical and modern control algorithms can be found in literature that have been modified for quadcopters, such as PID control [1][2], LQ control [1], backstepping control [3][4], feedback linearisation [1], adaptive nonlinear control [5], nonlinear PD control [1], sliding-mode control [5] and PD(2) control [1]....
