Modeling and control of distributed thermal systems
IEEE Transactions on Control Systems Technology, 2003This paper investigates the application of model-based control design techniques to distributed temperature control systems. Multivariable controllers are an essential part of modern-day rapid thermal processing (RTP) systems. We consider all aspects of the control problem beginning with a physics-based model and concluding with implementation of a ...

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 of a thermal system
Proceedings of IEEE International Conference on Control and Applications CCA-94, 1994The application of cascaded state-space control for thermal systems is presented. The use of an observer for the immeasurable states also enables the control of the difference between the two temperatures. For a large class of systems, a simple model is obtained. This model is parametrized by the accessible parameters like the caloric mass and the heat

A Thermal Control System for Thermal Cycling
Journal of Testing and Evaluation, 1985Abstract A microprocessor-based system has been developed to control varying temperature during material characterization tests. The system controls temperature independently over four zones. Four control zones are used in order to provide two-dimensional temperature control on a flat plate specimen.

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 ...

Optimal Control of a Nonlinear Thermal System
IFAC Proceedings Volumes, 1989Abstract An optimal control problem of a nonlinear theraal system is studied. The existence of an optimal solution is given. The problem is discretized by an implicit scheme in time and a finite elements method of first order in space. A convergence result of the discrete optimal solution towards the continuous optimal solution is worked out.

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
