摘　　要：通过对热驱动部件的理论分析,确定参数待定的热驱动部件温度数学模型。依据试验采集的大量数据,采用分段逐级拟合的方法,用此数学模型的输出曲线逼近试验数据得到的曲线,从而将模型中待定参数确定下来,获得热驱动部件温升数学模型;并将时间最优控制运用到此数学模型上,准确地获得预先设定的目标温度值。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.
