Friction and friction compensation in the Furuta pendulum [PDF]
1999 European Control Conference (ECC), 1999 Inverted pendulums are very well suited to investigate friction phenomena and friction compensation because the effects of friction are so clearly noticeable. This paper analyses the effect of fiction on the Furuta pendulum. It is shown that friction in the arm drive may cause limit cycles. The limit cycles are well predicted by common friction models.
