|Reduced Order Thermal Finite Element Models Using Modal Reduction|
|Keywords: Thermal Modes, Reduced Order, Finite Elements|
|To develop comprehensive thermal control strategies, reduced order thermal plant models provide a basis for real time simulations. In the past, highly developed control models for mechanical structures have been built using state-space models from modal reduced order complex structural FE models. Based on this same modal reduction technique, a Finite Element thermal plant model is developed for implementation into a closed loop time domain simulation. The thermal modes are found by performing an eigenvalue analysis, and a reduced subset of these thermal modes are used to construct a State-Space model. A review of the mathematical theory and application to the thermal control of circuit board are presented.|
