Summary: | 碩士 === 華梵大學 === 機電工程研究所 === 87 === In many engineering problems, such as space shuttles、boilers、combustion chambers、rapid thermal processing for the wafer…etc., the heat flux and temperature can not be measured by sensors installed at high temperature locations usually, while these informations are very important in the analysis and design of the systems. Therefore, the sensors must be located at lower temperature location. The physical quantities such as heat flux, temperature, thermal conductivity, and thermal diffusivity at the high temperature locations are estimated by the inverse analysis from the measured temperature data. Then, the purpose of real time control can be fullfilled.
In order to achieve the requirement of real time control, the theory of the observer is adopted as a basis. It is expected that the heat flux and temperature of the heated surface can be estimated simultaneously right after the measured temperature data have been taken. The advantages of the method are its ability of real time analysis, filtering measurement noise, and simpilicit.
In this thesis, the application of the observer in the inverse heat conduction problem is testified. The optimal correction factors are found out.
