For the present study, the aim is to maintain both the aircraft and the pendulum stable throughout the whole trajectory, even in the presence of parametric uncertainties and measurement errors. The system is modeled via Euler-Lagrange formulation considering both the dynamics of the Tilt-rotor UAV and the pendulum. As for the nonlinear control design, a three-level cascade strategy is proposed. Each level of the cascade system executes a control law designed through the method of input-output feedback linearization. Simulation results are carried out to corroborate the proposed control strategy.",

The main objective is, in the presence of exogenous disturbances, to ensure that the inclination angle of the pendulum (controlled DOF) is led to the upper vertical position, while the angular velocity of the wheels (the time-derivative of the remaining DOF) can be set in a desired reference value. Thus, the angular position of the wheels (remaining DOF) is driven to steady state, i.e., it is maintained stabilized (static equilibrium) (????=0rad/s), or at least its velocity (mechanical equilibrium) (????=const.rad/s). The proposed controller considers the whole dynamics of the system into its structure, ensuring that the overall system is closed-loop stable. Furthermore, an improvement of the nonlinear H??? control tuning method for mechanical systems is developed. Experimental results are carried out with a real two-wheeled vehicle in the presence of external disturbances, unmodeled dynamics and from extreme initial conditions.",

Prediction error and disturbance effects are analyzed in order to guarantee input-to-state stability (ISS) and robust constraint satisfaction in the presence of bounded disturbances. It is shown robust constraint satisfaction and ISS are ensured by imposing tighter constraints and a modified ISS condition to the dead-time free model. These modified specifications are derived in terms of a K function description in order to reduce Lipschitz constant conservatism. A numerical comparison based on the CSTR reactor model is presented to illustrate the advantage of the proposed approach.",

The helicopter motion equations is obtained by the Lagrange- Euler formalism. The control structure is performed through a nonlinear Hinfin controller to stabilize the rotational movements and a control law based on backstepping approach to track the reference trajectory. Finally, simulations results in presence of aerodynamic moments disturbances and parametric uncertainty is carried out to corroborate the effectiveness and the robustness of the strategy proposed.",
