摘要
根据热电偶测温系统的物理模型和数学模型导出校正函数,利用Z变换、离散信号的插值原理以及快速富里叶变换的算法、提高测温系统的响应快速性。此方法具有运算速度快,计算精度高和校正特性好等优点。
The correcting function Ls inferred by the physical model and mathematical model of a thermocouple temperature measuring system. The reaction rapidity of the temperature measuring system is raised by applying Z transform. The interpolation principle of discret signal and FFT algorithm. This method has much advantage such as fast operation, high computing precision and good correcting property.
