Abstract: The paper presents a robust integral of signum of error (RISE) controller for active suppression of flutter of a two-dimensional airfoil, and it is integrated with a general extended state observer (GESO). Toward this, ...

Abstract: The work presents optimized uncertainty and disturbance estimator (UDE) based robust controller to achieve the fixed wing micro-aerial vehicle (MAV) longitudinal and lateral stability. In the proposed control methodology, ...

Abstract: Grid fins are unconventional control surfaces consisting of an outer frame supporting an inner grid of intersecting planar surfaces. Although afflicted with higher drag, these have been credited for their enhanced lifting ...

Abstract: This paper presents an adaptive fault-tolerant controller using terminal sliding mode theory to control the wing-rock motion in a slender delta wing. The governing equations of motion of have been obtained using the unsteady ...
