A Finite-Time Fault-Tolerant Control Using Non-Singular Fast Terminal Sliding Mode Control and Third-Order Sliding Mode Observer for Robotic Manipulators
In this paper, a fault-tolerant control (FTC) method for robotic manipulators is proposed to deal with the lumped uncertainties and faults in case of lacking tachometer sensors in the system.First, the third-order sliding mode (TOSM) Breast Forms observer is performed to approximate system velocities and the lumped uncertainties and faults.This obs
