Application of PID in Position Control of Multi-Articulated Robotic Arms in Rock Drilling Trolleys

This paper studies the electro-hydraulic proportional position control system of a hydraulic rock drilling jumbo. First all, composition is introduced and transfer function components established, mathematical model whole finally obtained through calculation simplification. Then, PID fuzzy strategy were designed by MATLAB software, was built in simulink. Finally, results indicate that controller has better anti-interference ability, response speed more advantageous than PID.
