Delay system modeling of rotary drilling vibrations


Vibrations in rotary drilling systems are oscillations occurring without being intentionally provoked. They often have detrimental effects on the system performance and are important source of economic losses; drill bit wear, pipes disconnection, borehole disruption and prolonged drilling time. By this chapter, we provide an improved modeling for the rotary drilling system . Among others, the proposed modeling takes into account; the infinite dimensional settings of problem as well as the nonlinear interconnected dynamics.
