Design of Intellectualized Controller of Shield Machine

Abstract:

Based on the theoretical deduction of jack thrust, the historical data are analyzed and the relationship between geological condition and the thrust of jack is derived. In real-time control, the controller sets the value of the jack thrust based on the prediction of Radar. According to fuzzy control theory, the deviation thrust of jack is obtained on the basis of the automatic measuring system. With prediction thrust and deviation thrust, the controller controls the shield machine successfully.
