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 ...

Control system design for a rapid thermal processing system
IEEE Transactions on Control Systems Technology, 2001Proposes a control system design for a rapid thermal processing (RTP) system, which has four circular concentric lamp zones and four temperature sensors. The control system consists of a least square feedforward controller and an output feedback proportional plus integral (PI) controller. The goal is to maintain uniform temperature tracking for typical

Hierarchical Control of Aircraft Electro-Thermal Systems
IEEE Transactions on Control Systems Technology, 2020A hierarchical model predictive control (MPC) approach is developed for energy management of aircraft electro-thermal systems. High-power electrical systems on board modern and future aircraft perform a variety of mission- and flight-critical tasks, while thermal management systems actively cool these electronics to satisfy component-specific ...

Modeling and control for an integrated thermal hydronic system
2015 IEEE 28th Canadian Conference on Electrical and Computer Engineering (CCECE), 2015This paper presents modeling and control methods for an integrated thermal hydronic system (ITHS) consisting of a solar thermal collector, a thermal storage unit and a thermal booster. Control inputs are: valves activation time, pitch angle, solar pump rate and compressor rate, measurements are: temperatures at critical points, and disturbances are ...

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.

Power and Thermal Control System
1999Space stations represent the largest kind of infrastructures in space. As they are used intensively over long periods of time, it is not surprising that they are also the largest power consumers in space. Due to the current mode of power generation by means of solar generators, the large collector surfaces are the dominant components of a station ...

Space Thermal Systems - The Challenge of Adaptive Controls
SAE Technical Paper Series, 1984<div class="htmlview paragraph">The rapid and ever increasing development of microprocessor based controllers in a wide and diversified range of applications leads to consider their candidacy on spacecraft systems. Easy programmability, potentials for implementing the most complex logical control laws, and their “adaptivity” form the backbone of ...

An Intelligent Control System for Thermal Processing of Biomaterials
2007 IEEE International Conference on Networking, Sensing and Control, 2007An intelligent control system for thermal processing of natural biomaterials, based on machine vision, sensor fusion and neural network was developed. Experiments with ginseng drying showed advantages of machine vision for real-time imaging of morphological, colour and texture attributes, providing sufficient discriminatory information about ...
