A barrier function-based fixed-time fractional order sliding mode super-twisting control for robotic manipulators with actuator faults

Haicheng Wan, Yujuan Wang, Ping Wang

Considering the uncertainties, chattering, and actuator faults that may result in unexpected performance, this research proposes a fractional fixed-time super-twisting control scheme for robotic manipulators subject to uncertainties and faults without the need for disturbance observers. A novel fractional-order sliding manifold is …
