Modeling and Compound Control of Disk Brake Automatic Drilling System
This article modeled the disk brake automatic drilling system for the first time and pointed out its characteristics of high order and time-varying,what’s more,it is very sensitive to disturbance. In the drilling operation of deviated deep hole,compound control strategies with computer including cascade control and feed-forward control are introduced to eliminate disturbances which include the friction between drilling tools and borehole wall,the resonance of rope and drill pipes,and the vibrancy caused by downhole motors. The reliability and practicability of this automatic driller are increased by the adoption of PC (Programmable Controller). The field experiments shown that the computer control methods above can effectively suppress interference during the deviated deep hole drilling operation,achieving a satisfied and reliable control quality. In addition,the study and control methods about this drilling system have universal significance to the application of other automatic drilling systems.
