Total-Amount Synchronous Control Based on Terminal Sliding-Mode Control

open access: yesIEEE Access, 2017
This paper presents a total-amount synchronous control (TASC) strategy for nonlinear systems with uncertainty based on finite-time control theory. In combination with a new type of terminal sliding-mode control strategy, finite-time convergence of TASC ...

Integral sliding mode control for non-linear systems with mismatched uncertainty based on quadratic sliding mode

open access: yesThe Journal of Engineering, 2015
In this study, uncertainty and disturbance compensations are addressed for non-linear systems by an integral sliding mode (ISM) design. It is divided into two steps for implementation of the ISM control.
