Method for acquiring optimal value of attitude control parameter of shield tunneling machine

The invention relates to the technical field of shield tunneling machine control, in particular to a shield tunneling machine attitude control parameter optimal value obtaining method. Original data and tunneling parameters of an original shield tunneling machine are obtained; screening the propulsion loop data, the propulsion data and the normal operation data based on the original data to obtain screened data; preprocessing the screened data to obtain reference data; performing inversion processing on the tunneling data error based on the reference data to obtain a deviation weight; dividing the importance degree of the reference data to obtain an effect weight; dividing the influence degrees of the reference data at different moments to obtain time weights; the target parameter value is calculated based on the deviation weight, the effect weight and the time weight, the optimal value of the target control parameter can be obtained according to the historical construction data of the ...
