Approach in Theory of Nonlinear Evolution Equations: The Vakhnenko-Parkes Equation
Published 2016-01-01“…The VE, which arises in modelling the propagation of high-frequency waves in a relaxing medium, has periodic and solitary traveling wave solutions some of which are loop-like in nature. The VE can be written in an alternative form, known as the Vakhnenko-Parkes equation (VPE), by a change of independent variables. …”

Spatial Domain Adaptive Control of Nonlinear Rotary Systems Subject to Spatially Periodic Disturbances
Published 2012-01-01“…The first control module applies adaptive backstepping with projected parametric update and concentrates on robust stabilization of the closed-loop system. The second control module introduces an internal model of the periodic disturbances cascaded with a loop-shaping filter, which not only further reduces the tracking error but also improves parametric adaptation. …”

Adaptive control of uncertain non-linear fractional-order systems in the presence of actuator failures and input constraints
Published 2024-08-01“…By correcting parametric, structural, and environmental uncertainties, the controller ensures the asymptotic stability of the closed-loop system and output tracking. Stability analysis is conducted using the Mittag-Lefler stability theorem, and numerical simulations are performed to validate the proposed method.Findings: The simulation results demonstrate the effectiveness of the proposed method in compensating actuator failures and input constraints while achieving closed-loop system stability and output tracking.Originality/Value: This research offers an innovative contribution to the field of control systems by employing adaptive control for actuator failure compensation in non-linear fractional-order systems and presenting a comprehensive theoretical framework, addressing both practical and theoretical challenges.…”
