针对一阶惯性加纯滞后（first order plus dead time，FOPDT）模型，提出一种基于阶跃响应参数估计的新方法。该方法通过对模型输出变量的简单变换，将参数估计转换成一个最佳线性拟合问题。计算实例表明，利用该方法估计模型的参数是可行的，而且能够获得较精确的结果。

In this paper, a new method based on step response has been proposed to simultaneous estimate model parameters for first order plus dead time (FOPDT) model. The method is applied a simple transformation of the output variables of the model, and transformed the parameter estimating into an optimal linear fitting. A numerical example is employed to illustrate the feasibility and accuracy of the proposed method.
