Application of Self-adaptive Fuzzy Control on the Automatic Verticality Control of Rotary Drilling Rig

摘要

The factor of influencing drilling mast verticality is a lot.The controlling process has the characteristic of non-linearity,uncertainty and multivariable,so the mathematical model is difficult to establish.Combined the engineering practice of drilling mast verticality control,this paper build a self-adaptive fuzzy control model ,conduct a simulation and initial verification.Result shows that the self-adaptive fuzzy control make the tracing error achieve the expectant target and the system has high-quality and high-efficiency.
