摘要
针对旋转导向钻井稳定平台系统摩擦的不确定性,研究预测控制算法并将其应用于稳定平台的工具面角控制中。同时,利用Matlab软件的图形用户界面设计功能,设计稳定平台广义预测控制仿真平台。最后,通过仿真验证该算法的鲁棒性和控制精度。
This thesis studied the generalized predictive control algorithm, which is applied in the control system of tool face orientation, to solve the uncertainty of friction model of the control system of stabilized platform and to im- prove the accuracy and stability of the system. At the same time, Graphic User Interface （GUI） of Matlab was used to design a simulation of generalized predictive control, which provides convenience for human - computer interac- tion. The platform has the advantages of simple operation, strong interactivity and visualization. Simulation results show that the algorithm can guarantee good robustness and higher control precision.
