摘要:
分析了温度传感器动态特性的一阶系统模型和二阶系统模型,指出了其中的二阶系统是非欠阻尼系统、两个系统的阶跃响应有相似性和共同点,进而提出可以将温度传感器动态模型统一简化为一阶系统模型.推导了能够将该一阶系统补偿成理想全通系统的补偿电路传递函数,设计了能实现该传递函数的有源滤波电路,给出了依温度传感器热时间常数设计电路元件参数的公式.指出信号转换电路输出电压与传感器体温度成线性比例关系、补偿电路和信号转换电路有足够宽的通频带,是用硬件实现温度传感嚣动态特性完全补偿的两个必要条件.
Abstract:
The frst-order system model and second-order system model for dynamic characteristic of temperature sensor are analysed, The second-order system is not a underdamping system and that there are similarityand intercommunity belween the step responses of the two systems are pointed out, and then that the dynamicmodels of temperature sensor can be unifed simplified as the first-order system model is put forward, Thetransfer function of compensating circuit which can make a frst-order system to be compensated as a perfectall-pass system is derived. The active filter circuit which can realize the transfer function is designed, and thedesign formulas for calculating the circuit element parameters by therma! time constant of temperature sensorare given out. That the output voltage of signal conversion circuit are linear and proportionate to the sensor’stemperature, and that compensating circuit and signal conversion circuit have sufficiently wide pass band, arepointed out as the two necessary conditions realizing compleie compensation to dynamic characteristic of temperature sensor using hardwear.
