A novel control system design for automatic feed drilling operation of the PLC-based oil rig

Abstract

Aiming at the difficulties in realizing the accurate control due to the nonlinearity of the automatic drilling system of oil drilling rig, a design scheme is proposed by giving a constant drilled-pressure to the rig for fuzzy control. Sampling error with changes in the signal was sent into the fuzzy controller, which turned the signal into a fuzzy volume. Subsequently, a precise volume was obtained accordingly and then added to an actuator for the motor control. According to the MATLAB simulation results, the response could be faster and more stable compared with the traditional control.

An Intelligent Controller Based on LAMDA for Speed Control of a Three-Phase Inductor Motor

“…In this context, several investigations and real-field industrial applications that use control strategies implemented in PLC systems involve the use of Fuzzy control techniques, which are well documented in some works like [16][17][18][19][20]. On the other hand, the simplicity of fuzzy control logic implementation represents an opportunity to be used even at the microcontroller level [21].…”
