A study of a DRNN-based smart control experimental system for use with automatic bit feed on rig;

Fuzzy optimum control of automatic bit feed on rig;

Research on simulating experimental system for automatic bit feed.;

Research on Pressure Control System of Auto-drilling Based on Fuzzy Self-adaptive PID Theory;

Research on Bit Pressure Control System of Auto-drilling Based on BP Theory;

A fuzzy logic controller with an optimum weighting factor is worked out for automatic drilling experimental system.

A electrical drive system of the first 7000m module drilling rig in China is presented about its trait presened on the one line diagram,including SINAMICS S120 DRIVE-CLiQ topology,remote monitor and autodriller.

Aimed at the non-linearity,uncertainy and real-time requirements in drilling process,in simulating experiment,the autodriller is considered as controlled system and a controller system based on a fuzzy-PID.

The Intelligent Control System of Auto-driller;

The auto-driller is a kind of new control system according to the technology of oil-drilling.

And finally it makes a conclusion: Contrast with the other kinds of auto-driller systems driven by motors,the auto-driller system driven by small motor has obtained excellent application effect because of its following features: safety,reliability,easy for installation,and accurate control,etc.
