根据对象的输入输出采样数据，用数值计算方法分析热工对象模型的阶次。对于用曲线拟合方法建立热工对象的数学模型，本算法可以为模型阶次的确定提供依据。仿真例子表明，算法对无零点对象的分析结果是准确的。
According to the input and output of the sample data, numerical methods to analyze thermal engineering model order. The curve fitting method for the establishment of mathematical models of thermal objects, the algorithm can provide a basis for the determination of model order. Simulation examples show that the algorithm is accurate for zero-point object analysis.
