| 摘 要： | 单屏蔽式温度传感器一般用来测量发动机高速气流总温,本文依据其动态校准试验数据,采用系统辨识方法建立了它的动态试验数学模型.根据辨识的数学模型,采用一种快速的动态补偿算法,得出了传感器动态补偿器的传递函数,为下一步在硬件上设计实用的温度传感器动态补偿器打下了坚实的基础.

| Abstract: | The single-sheath temperature probe(SSTP) is widely used to measure the total temperature of gas flow in engine.This paper describes a dynamic modeling of the SSTP by the methods of system identification according to the dynamic calibration data of the SSTP.On the base of its modeling,a kind of fast arithmetic of dynamic compensation is used for getting transfer function of dynamic compensator of SSTP,which is the base for the hardware design of dynamic compensator of the SSTP. |
