Practical nonsingular terminal sliding-mode control of robot manipulators for high-accuracy tracking control
This paper presents a practical nonsingular terminal sliding-mode (TSM) tracking control
design for robot manipulators using time-delay estimation (TDE). The proposed control
assures fast convergence due to the nonlinear TSM, and requires no prior knowledge about
the robot dynamics due to the TDE. Despite its model-free nature, the proposed control
provides high-accuracy control and robustness against parameters variations. The
simplicity, robustness, and fast convergence of the proposed control are verified through …

This paper presents a practical nonsingular terminal sliding-mode (TSM) tracking control design for robot manipulators using time-delay estimation (TDE). The proposed control assures fast convergence due to the nonlinear TSM, and requires no prior knowledge about the robot dynamics due to the TDE. Despite its model-free nature, the proposed control provides high-accuracy control and robustness against parameters variations. The simplicity, robustness, and fast convergence of the proposed control are verified through both 2-DOF planar robot simulations and 3-DOF PUMA-type robot experiments.
