Theoretical Foundations of Adaptive Rotary Drilling Control

The article discusses the technological processes of cutting during drilling and the operation of technological equipment. The article considers the possibility of solving the problem of self-regulation, self-tuning of the machine to operating modes and parameters close to optimal by increasing the level of automation of the control process. The process of operation of an automated drilling machine was also studied, its characteristics were determined, the change in the strength of the material of the destroyed rock and other factors affecting the efficiency of the drilling process were studied. At the same time, it was revealed that the method of automating the drilling process using electronic automatic control systems and control systems with adjustable drives requires an accurate description of the characteristics of the material being destroyed and their variability, which is possible only with a certain degree of accuracy due to the stochastic nature of changes in these characteristics. Thus, there are no sensors in machines and units with an adaptive structure, feedback is carried out through kinematic links. At the same time, self-regulation can be provided within certain restrictive limits.
