Kalman estimation - Thermocouple

[M.Siddeq]

Hello

The attached VI is a trial to estimate a correction for a thermocouple measurements. The reference transfer function is converted to a state-space model to use it for the estimation of the actual temperature.

My problem is in the last block, the linear simulation VI, as I could not get the expected output. Could you please advice on how to configure the inputs to this VI.

Thank you

Hi,

it's hard to say. Maybe it's problem in your model. Did you try to recognize it via Probe Watch?

Thanks Simyfren

The model is simple, as you see in the VI, it was converted by by a built-in VI from a known transfer function. Moreover, it works in the discrete Kalman filter VI. So, I guess the problem might be in how the inputs excite the model in the linear simulation.
