The Roll Stable Control Simulation of the Servo Platform in Modular Controllable Stabilizer
调制式可控偏心器伺服平台的滚动稳定控制系统仿真

Rotary steering drilling equipment-modular controllable stabilizer is discussed. The roll stability of its servo platform are modeled and simulated. The simulation result appears that using the given control method the servo platform can keep the state of roll stability, when we change the drill operating parameter. With this characteristic we can control the lateral force bearing on the bit, thus the well profile can be controlled.
