Displacement Parameter Inversion for a Novel Electromagnetic Underground Displacement Sensor
Underground displacement monitoring is an effective method to explore deep into rock and soil masses for execution of subsurface displacement measurements. It is not only an important means of geological hazards prediction and forecasting, but also a forefront, hot and sophisticated subject in current geological disaster monitoring. In previous research, the authors had designed a novel electro...
متن کاملL1 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 کاملControl of a Rotary Steerable System Directional Drilling Tool Rollstabilised Control Unit
A directional drilling tool control unit whose design is based on servo control of a rotary valve using the roll-stabilised instrumented system approach has been successfully used in oil fields for over twenty years. In this paper, Field Oriented Control (FOC) is applied to cascaded voltage regulation and servo control using a open-loop plant model of the roll-stabilised control unit. The servo...
متن کاملA Flexible Real-time Motor Control System for Robot Joints
-A flexible, real-time motor control system consisting of a DC motor and an incremental optical encoder is proposed. The system allows complex real-time control algorithms to be implemented with hardware control excepting PC-based software simulation. A motion control processor is used to bridge the Target PC and the robot joint through I/O devices. Simulink/Real Time Workshop (RTW) are the sof...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
