Design of Autopilot for MAV using Nonlinear Dynamic Inversion

R Guruganesh

Abstract


Nonlinear dynamic inversion (NDI) is a very popular method employed in aircraft automatic flight control systems. NDI is based on the concept of feedback linearization. In this technique, the inherent dynamics of the system are replaced by the desired dynamics. This paper considers the dynamic inversion process employed in the design of altitude hold loop and heading hold loop for which the control inputs are the elevator deflection and aileron deflection respectively. The same technique is also employed to develop the automatic landing controller for the MAV. The landing maneuver is divided into glide slope and flare. Design of glide slope and flare trajectory is also presented in this paper. A nonlinear simulation is carried out using Black Kite 6DoF model in MATLAB/Simulink to assess the controller performance. The simulation results demonstrate the effectiveness of the method.
