Drillstring vibration is one of the limiting factors affecting maximization of drilling
performance and causes at the same time premature failure of drillstring components. The
polycrystalline diamond compact (PDC) bit enhances the overall drilling performance giving
the best rate of penetration with less cost per foot, but PDC bits are more susceptible to the
stick–slip phenomena, resulting in high fluctuations of bit rotational speed. Based on the
