This example models a triplex pump with a predictive maintenance algorithm that can detect which parts of the pump are failing simply by monitoring the pump output pressure.
The Simscape model of the pump can be configured to model degraded behavior due to seal leakage, blocked inlets, bearing wear, and broken motor windings. MATLAB code shows how to accelerate testing by reusing results from previous simulations. The model can be used to generate training data for the machine learning algorithm and can be used to test the deployed algorithm. MATLAB Live Scripts show you how to develop the algorithm.
Mechanical, hydraulic, and electrical parameters are all defined in MATLAB which lets you easily resize the pump. The pump housing is imported from CAD.

@Abhijit - contact me directly via my author page and send me your email and which release you want and I can email it to you. I have this example from R2017b and higher.
Wondering how I can open this file when I don't have 2019 version for export. Do you by any chance has the older versions as well?
Added R2019a version.
Added R2018b version.
Added R2018a version. Contact me for R2017b version.
