Application of fractional-order calculus in sliding mode control for hypersonic vehicles

In this paper, fractional-order calculus (FC) is applied in the sliding mode control of a generic hypersonic vehicle (GHV). In the design of the controller, dynamic inversion is applied to deal with strong couplings among pitch angle, yaw angle and roll angle. The effect of FC is evaluated in a sliding mode controller. Simulation results demonstrate that sliding mode controller becomes more robust and damping characteristic is strengthened by use of FC.
