The Thermal Canister: An Instrument Thermal Control System
SAE Technical Paper Series, 1983<div class="htmlview paragraph">The Thermal Canister is a proof of concept experiment flown on the third flight of the Space Shuttle (March 1982). The canister utilizes heat pipe technology to provide a closely controlled, stable temperature environment for scientific instruments negating the effects of the harsh, variable shuttle environment ...

Robust Control of a Thermal Unstable PDE System
2018 13th APCA International Conference on Control and Soft Computing (CONTROLO), 2018Some distributed parameter systems with irrational transfer function can be written into an infinite factorized quotient for dynamic analysis and control design purposes. Hence, high accuracy approximate time solutions and frequency uncertainty bounds can be computed exactly, enabling early lumping in robust controller design.

Thermal modeling and control of rapid thermal processing systems
Proceedings of 1995 34th IEEE Conference on Decision and Control, 2002Rapid thermal processing (RTP) is becoming increasingly more important in semiconductor wafer fabrication. A nonlinear physical model for a generic RTP system is described. This generic RTP system is representative of the state-of-the-art RTP systems. A low-order nonlinear model is developed.

Learning Control Approach for Thermal Regulation of Rapid Thermal Processing System
2015 IEEE International Conference on Systems, Man, and Cybernetics, 2015In order to control the temperature distribution on the wafer in a rapid thermal processing system, we develop a learning control approach based on the dominant modes of the system state. Firstly, the dominant modes of the system state are extracted through the K-L method.
