Abstract

In this paper, real implementation of an active fault-tolerant control for a robot manipulator based on the combination of an external linear observer and the super-twisting algorithm is proposed. This active fault-tolerant scheme uses an external linear observer to identify faults. Then, the fault information is used to compensate the uncertainties/disturbance and faults with the super twisting controller. Finally, the effectiveness of proposed control is verified by simulation and implementation for a 3-DOF robot manipulator. The results were illustrated that the proposed control can tolerate the relatively bigger faults due to the design of the observer and then show the better performances than the conventional super-twisting controller does.
