This paper deals with the design and implementation of the super twisting control algorithm for the attitude tracking of a four rotors helicopter known as quadrotor. The choice of this algorithm, which is based on the second order sliding mode technique, was justified by the fact that it ensures robustness with respect to modeling errors and external disturbances while reducing the chattering phenomenon...
This paper presents an adaptive backstepping attitude control method for a miniature helicopter with unknown parameters. The adaptive controller is designed by combining a control law with a parameter estimator, which provides estimates of unknown parameters. The stability of the overall closed-loop system is proven to be asymptotically stable based on the Lyapunov theorem. Computer simulation results...
In this paper we present the dynamic model and the stabilisation of an original configuration of an small helicopter having eight rotors. This configuration is not yet presented in the literature and in our knowledge is also the first prototype of this kind of helicopters. The equations of motion for the VTOL aircraft are obtained using Euler-Lagrange approach. Due to the configuration of the aircraft...
