  • METHOD AND DEVICE FOR FAULT ESTIMATION OF MEASUREMENT AND CONTROL DEVICE FOR ROTARY STEERABLE DRILLING SYSTEM
    Publication number: 20240133285
    Abstract: Provided are a method and device for fault estimation of a measurement and control device for a rotary steerable drilling system. The method for fault estimation includes: S1, establishing a state model of the measurement and control device for the rotary steerable drilling system; S2, establishing a fault-free model filter and a fault model filter, and initializing the fault-free model filter and the fault model filter; S3, detecting whether the measurement and control device for the rotary steerable drilling system has a fault; and S4, reinitializing the fault model filter under the condition that a detection result is fault-free; reinitializing the fault-free model filter under the condition that the detection result is faulty; and estimating, by the fault model filter, the fault in real time, and obtaining, by the fault model filter, the estimation value {circumflex over (x)}wf.
