L1 Adaptive Control for Directional Drilling Systems
This paper considers downhole directional drilling systems in the presence of unexpected variations in steering force, input delays, measurement noise and measurement delays, and explores the application of L1 adaptive controller for the trajectory control problem. The Explicit Force, Finitely Sharp, Zero Mass (EFFSZM) model is used for the steering system, in which spatial delays, modeling ina...
متن کاملAdaptive Control of a Vibratory Angle Measuring Gyroscope
This paper presents an adaptive control algorithm for realizing a vibratory angle measuring gyroscope so that rotation angle can be directly measured without integration of angular rate, thus eliminating the accumulation of numerical integration errors. The proposed control algorithm uses a trajectory following approach and the reference trajectory is generated by an ideal angle measuring gyros...
متن کاملTime-Varying Sliding Mode Adaptive Control for Rotary Drilling System
This paper presents a time-varying sliding mode adaptive controller in order to handle the stick-slip oscillation of nonlinear rotary drilling system. The time-varying sliding mode controller with strong robust has two time-varying sliding surfaces, one of them induced time-varying integral sliding mode control can control the transient stage of the rotary drilling system and ensure the system ...
متن کاملAdaptive sampling in digital control
This study provides a set of design curves from which effective digital control for an experiment can be obtained and at the same time efficient use of a digital computer shared with other experiments can be realized. The state variable technique is used as both a design method for obtaining the design curves for adaptive sampling and for predicting the states for control of the process. The ad...
متن کاملvibration drilling tool and thrust force investigation in vibratory drilling process of al 2024-t6
vibratory drilling (vd)process is a new modern technology where longitudinal wave with high frequency (more than 16 khz) and low amplitude (usually between 2 up to 30 µm) is superimposed on the movement of cutting tool, resulting in connection and disconnection of cutting tool engagement with workpiece. in this study, in order to perform vibratory drilling process, two vibration tools are desig...
