Adaptive Nonsingular Terminal Sliding Mode Control for Performance Improvement of Perturbed Nonlinear Systems

In this study, an adaptive nonsingular terminal sliding mode control technique according to the barrier function is designed for performance improvement and robust stability of nonlinear systems with outdoor disturbances. For reason, a novel surface presented based on states system. The forces system converge from initial conditions zero. Subsequently, non-singular scheme advised purpose finite-time switching surface. Finite-time stabilization verified by Lyapunov theory. against exterior perturbation, employed estimate unknown upper bounds disturbance. Finally, advantage productivity recommended method investigated simulation results. part, plasma torch jerk chaotic considered as case such that obtained results are given in different scenarios.
