Inversion Based State Estimation in Bioleaching Process with Measurement Noises

摘要：

In this paper, the assumed inherent sensor inversion (AISI) that is a soft-sensor in essence is used to perform the on-line estimation of the directly immeasurable state variables in the bioleaching process performed by Thiobacillus Ferrooxidans (T. ferrooxidans). The assumed inherent sensor (AIS) of the bioleaching process is first constructed successfully according to the systematic modeling algorithm proposed in our pervious work, and then the mathematical model of the AISI is obtained eventually after proving the invertibility of the AIS. Finally, the simulations are performed by using the AISI for such a bioleaching process with measurement noises. The simulation results show the effectiveness of the AISI.
