Control Aspects of Active Above-Knee Prosthesis

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.
