ABSTRACT:
An electronic pneumatic limb control system for a pneumatically actuated flexible limb is disclosed. The system includes a computer for providing signal data corresponding to a plurality of successive events of air introduction and non-air introduction, respectively, into the flexible limb during a predetermined limb movement. The computer signal data provides for time-varying the air introduction to the non-air introduction for the successive events thereof during the limb movement so as to minimize oscillation and overshoot. The system also provides for successive events of air exhaustion and non-air exhaustion to return the limb to a position of rest after the predetermined limb movement.
