A shifted or misaligned feedback loop gives rise to a two-point nonlocality that is the spatial analog of a temporal delay. Important consequences of this nonlocal coupling have been found both in diffusive and in diffractive systems, and include convective instabilities, independent tuning of phase and group velocities, as well as amplification, chirping and even splitting of localized perturb...

This paper focuses on the tracking and synchronization problems of hyperchaotic systems based on active backstepping method. The method consists of a recursive approach that interlaces the choice of a Lyapunov function with the design of feedback control. First, a nonlinear recursive active backstepping control vector is designed to track any desired trajectory in hyperchaotic Wang system. Furt...

In this article, a systematic procedure is given for determining robust motion control law autonomous quadcopters, starting from an input–output linearizable model. particular, the suggested technique can be considered as feedback linearization (FL), where nonlinear state-feedback terms, which contain aerodynamic forces and moments other unknown disturbances, are estimated online by means of ex...
