Abstract

This paper proposes a tracking control strategy of robotic manipulators using fractional-order sliding-mode with adaptive gain. The design methods of terminal sliding-mode and fractional-order terminal sliding-mode controllers are developed to implement the high-precision tracking control of rigid robotic manipulators. The control signals in the proposed controller are continuous. The chattering is attenuated and singularity is avoided by fractional-order terminal sliding-manifold. The control gain is adaptive to compensate the uncertainties in the control matrix of rigid robotic manipulators. Simulation results validate the proposed methods.
