Abstract Aimed at the features of verticality control system, i.e., non-linearity, uncertainty and multivariable, the control system of rotary drilling rig verticality based on self-adaptive fuzzy control was proposed in order to establish a high-quality and high-efficiency system which could be simply described. Through the simulation and experiment, it shows that self-adaptive fuzzy control algorithm makes tracing error achieve the expected target in a short time, and this control system has an outstanding control results. This verified the feasibility and effectiveness of the self-adaptive fuzzy control arithmetic for the rotary drilling rig verticality control system．
