  • Patent number: 11268370
    Abstract: Examples of techniques for model-based parameter and state estimation for directional drilling in a wellbore operation are provided. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes receiving, by a processing device, measurement data from the wellbore operation. The method further includes performing, by the processing device, an online estimation of at least one of a parameter to generate an estimated parameter and a state to generate an estimated state, the online estimation based at least in part on the measurement data. The method further includes generating, by the processing device, a control input to control an aspect in the wellbore operation based at least in part on the at least one of the estimated parameter and the estimated state. The method further includes executing a control action based on the control input to control the aspect of the wellbore operation.

  • Patent number: 10668931
    Abstract: A controller is configured to control a system by generating a control input to an actuator changing a state of the system in accordance with the control input. The controller includes an interface configured to receive data indicative of dynamic response of the actuator and a tuner configured to determine the maximum rate of change of the control input during a control cycle using the received data indicative of dynamic response of the actuator. The controller also includes a receiver configured to receive measurements of the state of the system and a solver configured to determine a current value of the control input for controlling the controlled system based on the state of the controlled system subject to constraints on operation of the system and a constraint on the maximum rate of change of the control input, and to cause the actuator to change the state of the system according to the current value of the control input.
