Quadrotor Control with a Guaranteed Presence of Output Signals under a Prespecified State Bounds

The article proposes a new robust tracking control method for UAV systems in roll and pitch angular planes. The main achievement of the obtained controller is a guarantee that the output signal is confined in a sufficiently small prespecified bounded set formed by arbitrary continuously differentiable functions. The method is applied to a multiple-input multiple-output quadrotor model under external bounded disturbances and parametrical uncertainties influence. Results and achieved performance are verified via representative computer simulation results.
