Study on Thrust Hydraulic System of TBM Based on AMESim MATLAB/Simulink Interface

摘要

The choice of fuzzy rules and membership function of fuzzy self-adjusting PID controller of tunneling boring machine (TBM)'s thrust hydraulic system exists the defect of subjectivity to a great extent. The genetic algorithm (GA) was adopted to optimize fuzzy rules and parameters of membership function and an improved PID controller based on GA was designed. In order to conduct the co-simulation, the mechanical model was built in AMESim and control model was designed in MATLAB/Simulink and co-simulation interface was used to carry out the co-simulation. The simulation results show that the improved PID controller can eliminate the overshoot and improved the response and steady state performance.
