| 摘 要： | 讨论了实际的带斜坡的阶跃激励信号的上升时间对测压系统参数辨识的影响。推导了其作为输入的二阶系统的时域输出表达式,根据输出表达式在加随机干扰的条件下对系统参数和激励参数进行了辨识,结果表明得到的辨识结果是正确的。

Dynamic character parameters identification of measuring pressure system |
| |
| Abstract: | ?That modeling parameters of measurement system for pressure in the time domain,which are affected by rising time of actual excitation step signal with slope,are discussed.Output formula of second order system excited by it in the time field is deduced.The parameters of measurement system and excitation signal are identificated according to output formula with white noise.It is shown that the identification result obtained is correct. |
