    Abstract: Systems and methods are provided for the control of a wind turbine. Accordingly, a wind classification module of a controller determines a current aerodynamic state of the wind resource based, at least in part, on a current operational data set of the wind turbine. The current operational data set is indicative of a current operation of the wind turbine. A configuration intelligence module of the controller then generates an estimated configuration for a turbine estimator module and a predictive control configuration for a predictive control module based, at least in part, on the current aerodynamic state. An operation of the wind turbine is emulated via the turbine estimator module to generate a control initial state for the predictive control module. The predictive control module then determines a predicted performance of the wind turbine over a predictive interval based on the control initial state and the predictive control configuration. The predictive control module generates a set point for at least one actuator of the wind turbine based on the predicted performance, and an operating state of the wind turbine is affected via the at least one actuator in accordance with the setpoint.

    Abstract: A system for determining a real time solid flow rate of a solid-gas mixture is provided. The system includes multiple sensors, a data-fusion unit and an estimating unit. The sensors generate multiple measurement signals for obtaining at least two measured values of the real time solid flow rate. The data-fusion unit receives the measured values and establishes a state-space model based on the measured values. The estimating unit estimates the state-space model to generate an estimated value of the real time solid flow rate. A method for determining a real time solid flow rate of a solid-gas mixture is also presented.

    Abstract: A rotary steerable drilling system includes a collar, a drill bit, and a bit shaft connecting the drill bit to the collar. The bit shaft is coupled to the collar through a joint capable of transmitting a torque from the collar to the bit shaft and is swingable with respect to the collar around the joint. The system, further includes first eccentric wheel and second eccentric wheel coupled to the bit shaft and rotatable to swing the bit shaft with respect to the collar around the joint to change a drilling direction, a controller for controlling the first eccentric wheel and second eccentric wheel to harmoniously rotate such that the swing of the bit shaft substantially compensates rotation of the bit shaft, and an active stabilizer mounted on the bit shaft and capable of pushing the bit shaft to deviate to cause a lateral displacement and a tilt angle of the drill bit.

    Abstract: A drilling system includes a drill string for connecting with a drill bit for drilling a borehole, a fixed stabilizer fixed on the drill string, and an active stabilizer including a body and actuators connecting the body and the drill string. The actuators are capable of driving the drill string away from a center of the borehole with a displacement. The body has an outer surface for contacting a wall of the borehole, an inner surface facing the drill string, and at least one guiding portion projecting from the inner surface and each defining at least one groove. The drill string includes at least one sliding portion slidable within the at least one groove respectively to constrain movement between the drill string and the active stabilizer along an axial direction of the drill string and guide movement between the drill string and the active stabilizer perpendicular to the axial direction.
