Abstract
This paper describes the control architecture of a
10 DOF (Degrees of Freedom) lower limbs exoskeleton
for the gait rehabilitation of patients with gait
dysfunction. The system has 4 double‐acting rod
pneumatic actuators (two for each leg) that control the
hip and knee joints. The motion of each cylinder’s piston
is controlled by two proportional pressure valves,
connected to both cylinder chambers.
The control strategy has been specifically designed in
order to ensure a proper trajectory control for guiding
patient’s legs along a fixed reference gait pattern.
An adaptive fuzzy controller which is capable of
compensating for the influence of the dry friction was
successfully designed, implemented and tested on an
embedded real‐time PC/104.
In order to verify the proposed control architecture,
laboratory experiments without a patient were carried
out and the results are reported here and discussed.
