Parameter identification and pressure control of dynamic system in shield tunneling using least squares method

  • Published:
Journal of Coal Science and Engineering (China)

Abstract

An estimation approach using least squares method was presented for identification of model parameters of pressure control in shield tunneling. The state equation of the pressure control system for shield tunneling was analytically derived based on the mass equilibrium principle that the entry mass of the pressure chamber from cutting head was equal to excluding mass from the screw conveyor. The randomly observed noise was numerically simulated and mixed to simulated observation values of system responses. The numerical simulation shows that the state equation of the pressure control system for shield tunneling is reasonable and the proposed estimation approach is effective even if the random observation noise exists. The robustness of the controlling procedure is validated by numerical simulation results.
