Abstract
Disclosed are embodiments of a volitional controller and prosthetic leg system comprising a volitional controller and a powered prosthetic leg. The volitional controller may be configured to control a powered knee joint and a powered ankle joint to enable a user to walk at different speeds and inclines. The orientation of the components of the powered prosthetic leg may be monitored continuously to enable the system to adapt to changes in the duration of the user's gait. The volitional controller may be configured to determine a target knee torque and a target ankle torque that may be based on the global shank orientation, a prosthetic knee velocity, and a prosthetic ankle velocity.
