基于T-S模型的钻杆对中自适应预测控制

T-S model based adaptive predictive control in drill stems windage adjusting

为非线性系统建立 T- S模糊模型 ,采用基于 T- S模型的局部递推最小二乘法对模糊规则后件参数进行辨识 ,然后用一步预测控制的方法进行控制。在钻杆对中控制中 ,定义了矢量化的时间为控制量 ,采用上述方法 。

A T S fuzzy model is established for nonlinear systems. Local recursive least square method is used to identify the sequence parameters of fuzzy rules. One step predictive method is adopted in system control. The method is applied to drill stems windage adjusting where directional time is defined as control action. The application results show the effectiveness of the proposed method.
