Design Closed-Loop Measurement and Control System of Drilling Rig
In order to overcome the deficiencies of outdated hydraulic system of drilling rig, The testing drilling system is designed, which provides drilling parameters of inspecting, recording and controlling to meet the need of high power and complex drilling controlling. Meanwhile, the improved incremental PID and the multiple algorithm of Fuzzy-PID realize closed-loop feedback control of drilling pressure and rotary speed, what enhance the control system stability and accuracy, and achieve the sake of good control effect so that the system achieves the targets with speed range from 0 to 160r/min and pressure range from 0 to 20MPa.
