Finite-time robust stabilization for a class of high-order nonlinear systems with multiple uncertainties and external disturbances

The paper investigates the problem of adaptive finite-time robust stabilization for a set high-order uncertain nonlinear systems in presence asymmetric output constraint, dynamic uncertainty and complicated external disturbances. Via effectively integrating artful Barrier Lyapunov Function (BLF) conjunction with continuous control armed serial integral functions consisting embedded sign operations, controller is generated, which promises that closed-loop system’s states converge to compact within finite time whilst preserving validity constraint. Preferable current techniques, suggested methodology unifies construct theoretical evaluation constrained unconstrained as well being able concurrently handle constraints, zero dynamics complex Finally, an instance simulation included illustrate established methodology.
