| 摘 要： | 对象参数辨识是高精度温度智能控制的关键技术之一.介绍一种在阶跃激励条件下,利用系统响应曲线上等间隔三组测量数据来识别被控对象参数的方法,推导出了参数辨识的计算公式及公式应用判断条件.通过计算机仿真实验,获得了辨识对象参数的阈值取值范围,结果显示即使在较强噪音情况下,仅对采样信号使用平均值滤波,就可获得满意的参数识别精度.

| Abstract: | The controlled object parameter identification is one key of the high-precision temperature intelligent control.A method of identifying the controlled object parameter is introduced under the step drive condition by using the system response with the equal-space three groups of metrical data,and gave the parameter identification formula and the formula application judgment condition.Through the computer simulation experiment,the threshold value scope of the identified object parameter is obtained.And the re... |
