Powered Prosthesis Locomotion on Varying Terrains: Model-Dependent Control with Real-Time Force Sensing [PDF]
RA-L 7(2):5151-5158, 2022, 2021 Lower-limb prosthesis wearers are more prone to falling than non-amputees. Powered prostheses can reduce this instability of passive prostheses. While shown to be more stable in practice, powered prostheses generally use model-independent control methods that lack formal guarantees of stability and rely on heuristic tuning.
