Abstract :
In this article, a non-linear PID structure is being synthesized, providing ameliorated compensation of the Pneumatic Artificial Muscle´s (PAM) non-linear hysteretic phenomena and advanced robustness. Experimental studies are being utilized to prove the overall efficiency of the non-linear control scheme regarding: a) set-point tracking performance for the position control of a single PAM and torsion angle control of an antagonistic PAM setup, as well as b) disturbance rejection in both single and antagonistic control scenarios.
