【 摘 要 】

The present work discloses the scheme of the automated control system that allows automated leaving the vibration mode by the drilling machine with the indirect vibration measuring method. In addition, the system allows entering the constant power method by the engine. This paper presents a system simulation and reveals that the machine spinner electric drive engine facilitates operating the working branch of mechanical characteristics in the mode of maintaining the set speed to the maximum torque (power specified), followed by moving into the constant power mode that facilitates moving the machine off the vibration zone by means of a small decrease of the drilling string rotation frequency. The article proves that the most radical automation approach suggests using the asynchronous engine drive vector control system in a manner that provides the best regulation accuracy possible.
