Hi Mohammed Lamine Mekhalfia ,

I am not really sure about the sensor that you want to simulate and develop but I can generally guide you that there are some software where you can simulated the actual environment. COMSOL and Solidworks are two examples of such software and I am sure there will be many more. I have used COMSOL for some electromechanical sensor simulations but there are many other modules which can be used for many other simulations.

Thanks

Numerically generated Gaussian white noise is often used for modelling/simulation applications. ― While investigating adaptive control and energetic optimization of aerobic fermenters, I have applied the recursive least squares algorithm (RLS) with forgetting factor (RLS-FF) to estimate the parameters from the KLa correlation, used to predict the O2 gas-liquid mass-transfer, while giving increased weight to most recent data. Estimates were improved by imposing sinusoidal disturbance to air flow and agitation speed (manipulated variables). The proposed (adaptive) control algorithm compared favourably with PID. Simulations assessed the effect of numerically generated white Gaussian noise (2-sigma truncated) and of first order delay. This investigation was reported at (MSc Thesis):
