摘要:
针对用于瞬态高温测量薄膜热电偶的动态特性研究问题,提出通过建立传感器的动态逆模型补偿器,来展宽其工作频带,以此来减小动态误差的方法.该方法无需事先已知薄膜热电偶的动态特性,可根据传感器以及参考模型对输入激励响应的实测数据,通过微粒群(PSO)算法的优化学习得到动态逆模型补偿器的参数.薄膜热电偶的输出经过补偿器后,能够克服由动态特性引起的测量误差.最后,通过实验验证了该方法的有效性.
Abstract:
On the study of the dynamic characteristic of the thin-film thermocoup le used in transient high temperature measurement, an app roach that can widen the working frequency band and reduce the dynamic error is reported by u2 sing the compensator of sensor dynamic inverse model. With this app roach, a compensator of sensor dynamic inverse model can be realized without knowing the dynamic characteristics of thin2film thermocoup le, and the parameters of the compensator are op timized by PSO algorithm according to the measurement data of the step response of the sensor and reference model. When the output signals of the thin - film thermocoup le are p rocessed by the compensator, the dynamic measurement errors are reduced. Experimental results show that the app roach is effective.
