Abstract :
In this paper, three disturbance estimation algorithms are experimentally evaluated by considering the control problem of a rodless pneumatic cylinder. Three disturbance estimation algorithms are then employed to compensate for this lumped disturbance: they are the traditional linear disturbance observer (TDOB), the integral sliding-mode disturbance observer (I-SDOB) and the IMP-based SDOB (IMP-SDOB). Experimental results are presented to compare these three algorithms in terms of positioning accuracy.
