Design of a Super Twisting Sliding Mode Controller for an MR Damper-Based Semi-Active Prosthetic Knee

Dawit Assfaw, Solomon Seid
2022 Frontiers in Robotics and AI  
In contribution toward such a gap, this study proposes the modeling and design of a robust controller for magnetorheological (MR) damper-based semi-active prosthetic knee.  ...  The numerical simulation results show that the super twisting sliding mode controller improves the semi-active prosthetic knee's tracking efficiency.  ...  Semi-active knees are mostly known for their use of magnetorheological (MR) fluid (MRF)-based mechanisms, for instance, MR dampers.  ...

2021 Applied Sciences  
In addition, to solve the problems of uncertainty and external interference in the MR prosthetic knee joint system, a second-order sliding mode controller was proposed.  ...  This paper developed a new magnetorheological (MR) prosthetic knee joint using an MR damper as the brake.  ...  However, they have the disadvantages of complex structure, cumbersome control and low stability [6, 7] . An MR prosthesis is a semi-active prosthesis based on an MR damper.  ...
