Active Control in Structures

In this paper the application of control theory to structural engineering has been presented from a structural engineering perspective. The objective of this paper is to summarize key steps that are required to design an active control system for a structure. Total...

Model-Based Control of MOCVD Rate, Uniformity and Stoichiometry

A 2D model of MOCVD reactor has been developed for deposition of YBCO thin films. System characterization showed the need for control of growth rate, deposition uniformity, and oxide stoichiometry at the surface. A run-to-run control architecture was developed, and is...

A Physical Model for Drying of Gelcast Ceramics

Gelcasting is a promising new technology for manufacturing advanced structural ceramic components. The process involves drying of the ‘green’ gelcast part before densiï¬cation. The physical mechanisms controlling this relatively long drying process are...
