This paper presents a method for optimizing the digital PID parameters on the basis of object unit-step response curve.
本文介绍了根据对象阶跃响应曲线进行数字PID调节器参数最优整定的方法。

The non-parametric models of the unit-step response and frequency response and the dynamic performance index of both in time domain and in frequency domain are also given in this paper.
文中还给出了单位阶跃响应和频率响应两种非参数模型，以及时间域和频率域的动态性能指标。

It is more reasonable that the dynamic performance index both in frequency domain and in time domain should be calculated from model calculated frequency response and unit-step response.
