Concepts of an Advanced Cartesian Control System for a Redundant Twin Boom Drill Rig
نویسنده
چکیده
The handling of complex machines such as redundant manipulators requires appropriate control systems in order to make the operating of the system easier and to reduce processing time. This paper presents an advanced control system for a drilling rig used in tunnel construction which is currently under development in cooperation with an industrial partner. The drill rig is equipped with two redundant drilling booms each actuated by eight hydraulic drives. The main objective of the project is the improvement of manual handling of the redundant drilling booms. For this reason, a Cartesian control concept based on a special kind of the generalized inverse Jacobian is used to calculate in real-time the inverse kinematics on velocity level. Furthermore, collision avoidance strategies will be implemented to achieve real-time collision avoidance while operating the two booms at the same time. Another important aspect is the development of a graphically supported man-machine-interface which enables an easy handling in manual and automatic control modes.

متن کاملSub and Supercritical Decontamination of Oil-Based Drill Cuttings: A Review
Drill mud is a fluid which is used in oil extraction industries in order to cool and lubricate the drill bit. Due to containing numerous toxic components, it is considered as a hazardous waste which must be treated before discharging to the environment. Current separation techniques for drill cutting treatment can be categorized into three main categories of physical (dewatering), physiochemica...

Sprayers are important tools in agriculture that usually moved on the field by tractor. Sprayers should distribute the constant rate of chemicals during various conditions encountered in the field. Unwanted vibrations of sprayer boom cause redaction of its life time and over doses and under doses of chemical sprayed on the field. Therefore, in this study a model of suspension system for rotatio...

The optimal path planning of cooperative manipulators is studied in the present research. Optimal Control Theory is employed to calculate the optimal path of each joint choosing an appropriate index of the system to be minimized and taking the kinematics equations as the constraints. The formulation has been derived using Pontryagin Minimum Principle and results in a Two Point Boundary Value Pr...
