| 摘 要： | 本文利用有关文献中介绍的四种方法对一个二阶有自衡能力的对象的阶跃响应进行了分析对比,论述了各种方法的优缺点。在一个气动模拟装置上测取一条阶跃响应曲线,用相关最小二乘二步法对其动态特性进行测定,得出各种方法的传递函数。结果表明,相似图解法精确度接近面积法,计算简单;Naslin法精度差;最小二乘法不能用于处理阶跃响应数据。

| Abstract: | In this paper four methods used to determine the transfer function of a second order linear system with transient response to the step function input are analysed and compared with each other. The behavior of a transient response curve is measured with ordinary least square method and calculated with four methods. The transfer functions with different methods have been obtained. The results show that simulation graphical method is better than others. The ordinary least square method can not be used to deal with the transient response to the step function input. |
