Quadrotor control using feedback linearization with dynamic extension

The contribution of this paper is the development of a nonlinear position controller for a quadrotor VTOL aircraft using feedback linearization with dynamic extension. The developed controller completely decouples and linearizes the nonlinear dynamical model of the aircraft. The use of dynamic extension has resulted into a fourteenth dimensional controller for the the twelve dimensional state system. Simulation results are provided to demonstrate the effectiveness of the nonlinear controller in tracking time-parameterized trajectories in inertial frame with internal stability.
