Constrained controllability of nonlinear systems [PDF]
Proceedings of the 2003 American Control Conference, 2003., 1995 This paper contains constrained exact local controllability results for nonlinear abstract differential equations. A generalization of the open mapping theorem is used for the sufficient conditions to guarantee controllability. The values of controls are in a convex, closed cone with vertex at 0.

Geometric Surface-Based Tracking Control of a Quadrotor UAV
, 2018 New quadrotor UAV control algorithms are developed, based on nonlinear surfaces composed of tracking errors that evolve directly on the nonlinear configuration manifold, thus inherently including in the control design the nonlinear characteristics of the

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
