| Abstract: | According to the theoretic study on thermal drive-part, a mathematical model with undecided parameters is given. Based on the abundant experiment datum and the gradual-subsection fitting method, all the undecided parameters are fixed through the approach of the output curve of mathematical model to the curve of experiment datum, then the real model of thermal drive-part is obtained. Optimum control is applied to this model and a precise result of temperature-rise is gained. |
