Abstract

We present the review of two approaches for control system design. These are: (i) Non-Linear Inverse Dynamics and (ii) Variable Structure Control; These two schemes of design are applied to a realistic aircraft flight model. The equations of motion are highly nonlinear and the design of a control system for large roll-coupled maneuvers is not a simple task. Analytical derivations of control laws are presented in this thesis for the maneuver of the aircraft using inversion and variable structure control techniques. A short theoretical treatment of each technique is developed and their applications to flight control design are presented; Several cases of flight conditions are simulated and the resulting data is analyzed and compared. The simulation results are presented to show that, while both techniques can control the system, the Variable Structure Control has a greater ability to control the model with less error and reduced sensitivity to perturbations.
