Control aspects of active above-knee prosthesis

https://doi.org/10.1016/S0020-7373(05)80159-2Get rights and content

A methodology for control of an active above-knee prosthesis (AKP) is described. This approach is called Artificial Reflex Control (ARC), and depends on the use of production rules, so that the controller may be thought of as a leg movement expert. This control strategy is applicable to a variety of different gait modes. Automatic adaptation, according to the environment, and to the gait mode required, is based on heuristics related to human motor control.

      Nevertheless, the actively controlled prosthetic systems are necessary to mimic the ankle characteristics during walking at fast walking speeds and for other activities rather than level walking. In order to remove insufficient features of passive assistive devices, researches are being maintained for developing actively controllable lower extremity orthoses [5], and prostheses such as Belgrade leg [6], an actively controlled above-knee prosthesis [7], Series Elastic Actuator [8,9], Sparky leg by Thomas G. Sugar's laboratory at Arizona State [10,11], and active below and above knee prostheses by Michael Goldfarb's laboratory at Vanderbilt [12,13]. Some trajectory control methods with rule-based control approach developed by sensor signals and previously acquired walking gait data are implemented for control of these active prostheses.
