Real-World Automation: New Capabilities for Underground Longwall Mining

This paper describes successful industrial research and development in the area of underground coal mining equipment automation. A brief background to underground coal mining is given, and the process of longwall mining is detailed. Some of the major limitations and issues impacting on the productivity and safety of the longwall mining process are highlighted, which serve to motivate the automa...

A new methane control and prediction software suite for longwall mines

This paper presents technical and application aspects of a new software suite, MCP (Methane Control and Prediction), developed for addressing some of the methane and methane control issues in longwall coal mines. The software suite consists of dynamic link library (DLL) extensions to MS-Access written in C++. In order to create the DLLs, various statistical, mathematical approaches, prediction ...

New control strategies for neuroprosthetic systems.

The availability of techniques to artificially excite paralyzed muscles opens enormous potential for restoring both upper and lower extremity movements with neuroprostheses. Neuroprostheses must stimulate muscle, and control and regulate the artificial movements produced. Control methods to accomplish these tasks include feedforward (open-loop), feedback, and adaptive control. Feedforward contr...

Viscoelastic damping for noise control in an armored military vehicle

Armored military vehicles have a harsh noise environment and many times the noise levels become almost an afterthought for the vehicle designers. There are numerous noise sources such as the engine, transmission, cooling fans, and track noise. The thick armor plating and the fact that the noise sources are inside the vehicle exacerbate the noise problem. This means there are few paths for the n...
