Abstract :
The identification procedure for nonlinear control system of shield machine tunneling is proposed by using neural network. Based on nonlinear constitutive model of soil and mass conservation law, the difference equation of nonlinear discrete system is deduced. Bp neural network is applied for an identifier to estimate model parameters of time varying control system. The numerical simulation shows that the identification procedure is effective for nonlinear and time varying control system in shield machine tunneling.
