“…For Quanser table-mount helicopter platform, past works show that state-feedback methods can achieve good dynamic and static performances even in aggressive maneuvers [17], while experimental results on output-feedback approaches are very limited. Kutay et al [21] gave the first experimental results of an adaptive output feedback approach for pitch axis only of the platform, but the coupling and high nonlinearity in multi-axis cases were not discussed. Rosales et al [20] presented results for three axes control but only set-point regulation problem was considered and the performance was limited.…”

“…The advantages of this experimental system, the 3DOF Quanser helicopter [1], are its reasonable small size, which allows to test some control laws with a high level of safety, and the possibility to evaluate advanced attitude controllers versus perturbations (thanks to the use of domestic fans). Without being exhaustive, the following list of previously published results [2][3][4][5][6][7] shows that many works have been made for the design of linear/nonlinear attitude controllers. Note that all these works have made some hypothesis on the structural properties of the system (for example, controllers based on singular perturbation theory [8][9][10]); on the mechanical architecture, however, all these assumptions highly reduce the realism of the simulations.…”
