YAN Bin~1, DANG Xuan-ju~2. Modeling and intelligence compensation to hysteresis of high molecular humidity sensor[J]. 2006, (7): 43-45+49. DOI: 10.13873/j.1000-97872006.07.014.
Due to the hysteresis characteristic of the high molecular humidity sensor exists in the process of measurement
it has influence on precision of measurement.According as the property of segmented linearity which the behavior of hysteresis exhibit is similar to the principle of Takagi-Sugeno(T-S) fuzzy modeling
a model is built on the T-S fuzzy modeling to the behavior of hysteresis nonlinearity of high moltcular humidity sensor.The inverse model of the hysteresis is established
which is put forward to make intelligence compensation to the hysteresis.The results of simulation show the hysteresis of humidity sensor is reduced from 5.56 %RH to 0.045 %RH after the compensation.
