Hey everyone!
I'm completely new on Control Systems, I came from a biotechnological background, but I'm interested on getting the transfer equation of a conductivity probe used in the laboratory to determine the blending time of a bioreactor. After comparing these results with the CFD values, I'm suspecting that the conductivity sensor is introducing some kind of delay and overestimating the results. I was told I needed to determine the transfer equation of the sensor to perform a deconvolution of the conductivity experimental data to get the "real" data. The sensor was tested moving the probe between two solutions to get the data/curve for the step up (not in the experimental bioreactor) (analysis data). I started in Excel by adjusting the analysis data to a first-order step function where a tau (time-constant) was estimated from replications. However, I have no idea how to continue to get the transfer equation. I tried some scripts in Matlab but the results make no sense. How Can I correct the conductivity experimental data set? Many thanks in advance ![]() |
