二阶传感器动态响应中暂态过程的研究

Research on Transient Process of Second Order Transducer Dynamic Response

用拉谱拉斯变换对二阶传感器系统的暂态过程进行了研究。研究表明二阶传感器系统在任意信号激励下存在直接进入稳态响应而不经历暂态过程的必要条件和充分条件。以正弦激励信号为例,得到了任意二阶系统在正弦信号激励下直接进入稳态响应的条件。

The transient process of second order transducer system is researched using Laplace transform. The results indicate that the necessary condition and sufficient condition of the directly entering steady-state response for the second order transducer system, at excitation of an arbitrarily signal, are existent. As an example, the second order transducer system at excitation of sinusoidal signal is demonstrated.
