Research on the Position Control Method of Cutting Head of Tunneling Machine Based on Optimized PID Algorithm
In response to the problems of low accuracy,poor control performance,long output response time,and weak system anti-interference ability in the traditional cantilever tunneling machine cutting head position control method,the cantilever tunneling machine position control technology was studied,the structural composition of the cantilever tunneling machine was analyzed,and a kinematic model of the tunneling machine cutting head was constructed.Propose fuzzy PID control and optimize PID controller,and conduct simulation research in MATLAB.The results show that the optimized PID controller reduces the output response time from 0.45 s to 0.32 s,significantly improving the system's response speed and anti-interference ability.The use of fuzzy PID control algorithm results in a faster output response,smaller overshoot,and greatly improved system stability.The research conclusion can provide a certain theoretical reference for the related research on intelligent control of cantilever tunneling machines.
