Robust compensation of a Cart–Inverted Pendulum system using a periodic controller: Experimental results

Based on Das and Dey (2007), this paper designs and implements a periodic controller to achieve, via zero-placement, robustness of a physical Cart–Inverted Pendulum system with respect to differential gain variations in the output sensors. Experimental results that verify the superiority of this controller over linear time-invariant (LTI) ones are also presented.
