Abstract :
A software structure is described that has been developed for the implementation of feedback controllers for standing, gait, and stair climbing using functional neuromuscular stimulation (FNS) in paralyzed individuals. The control structure has two levels. The upper level controller monitors the progression of the controlled system through a finite set of allowable states. The occurrence of particular events marks the transition of the system from one state to another. In each state a specified set of lower level controllers is used to achieve certain tasks.<>
