通过对旋转导向钻井稳定平台控制原理的深入研究,提出了采用串级模糊算法对稳定平台控制的方法。并设计出二维模糊控制器,确定了模糊变量的隶属度函数及控制规则,且利用MATLAB软件进行了仿真研究,仿真试验表明稳定平台串级模糊控制对钻井参数在较大范围内变化以及负载扰动对平台的影响,具有良好的稳定性、自适应性、鲁棒性且抗干扰能力强。

The control principle of the servo platform in rotary steerable drilling system was studied.To control the stabilized platform, cascade fuzzy algorithms is presented. A two-dimensional fuzzy controller is designed, the fuzzy variable degree of membership function and the control rule are determined, and the simulation research using the MATLAB software is studied. The simulation showed that stabilized platform using cascade fuzzy control system on a wide range of parameters change, disturbance and load disturbance parameters such issues, has a good stability, adaptability, robustness and anti-jamming capabilities.
