Abstract
The invention provides a system for automatic control of the drilling an oil well. The system includes an autodrilling interface enabling parameter input data to be input and enabling the display of system output data, a controller, a hydraulic control system and at least one sensor configured to the hydraulic control system. The controller receives parameter input data from the autodrilling interface and at least one sensor and provides output instructions to the hydraulic control system such that the hydraulic control system operates to control drilling based on controller instructions and sensor data.
