Abstract:

The principle of the fuzzy control of the surface settlement during shield tunneling is analyzed and summarized on basis of the automatic shield tunneling control technology. First, the structure of the controller is designed; Second, reasonable input and output variables of the controller are selected on basis of Matlab fuzzy control toolbox; Thirdly, useful fuzzy control principle for shield tunneling are obtained on basis of the manual control experience and expert knowledge; Finally, the design of the fuzzy controller is completed by offline working out the control table of the fuzzy controller on basis of Matlab.

Key words: shield surface settlement  , fuzzy control  , Matlab
