盾构智能化姿态控制器的设计

Design of Intellectualized Controller of Shield Machine

摘要:

在理论推导千斤顶推力的基础上,寻求工程历史数据的规律,得出地质条件与盾构推进千斤顶压力的关系.在控制器实时控制中,根据探地雷达探测得到的盾构前方的地质条件,控制器预设盾构各区千斤顶的压力值.引入模糊控制理论,根据自动测量系统测得的实时偏差量,通过模糊控制器得出千斤顶纠偏控制量.最后,综合推估推力和纠偏推力,最终实现盾构推进姿态的自动控制.

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.
