Hi @MADUKA CHIKA

I came across a relevant paper titled "PID and Novel Approach of PI Fuzzy Logic Controllers for Active Surge in Centrifugal Compressor," but it may not provide extensive insights into the design of a Mamdani fuzzy controller. You can find the paper here:

https://link.springer.com/article/10.1007/s13369-013-0601-6

However, if you have experience in designing classical PI or PID controllers, or state feedback controllers for stabilizing surge in centrifugal compressors, I can assist you in designing a Sugeno fuzzy controller instead. In fact, the paper's Mamdani fuzzy controller design approximates the Sugeno Fuzzy Controller. Why not consider designing a Sugeno Fuzzy Controller as an alternative?

Hi @MADUKA CHIKA

I dedicated an hour to speed-reading all 33 pages of the document, but I couldn't locate the mathematical model of the centrifugal compressor. In Equation 28, I noticed an ordinary differential equation (ODE), but I'm uncertain if it qualifies as a comprehensive model for controller design. It seems rather simplistic. It's possible that I may have overlooked it.

To save both of us time and ensure efficiency, would it be possible for you to directly provide the differential equations that include the control variable? Ideally, the model should resemble the one presented in Chetate et al., 2013.

P.S.: I also suggest that you share a copy of your progressive work with your supervisor for review and advice. I noticed that there are quite a few filler materials that could be omitted or condensed. A solid methodology should provide a comprehensive overview of the compressor system and its components (such as the sensor transmitter, process controller, and actuating valve). It should cover topics like surge, preventive measures against surge, available valve manipulation methods, their advantages and disadvantages, and finally, delve into the focal point of your research, which is the Fuzzy Logic-assisted Control Scheme.

Unlike ordinary compressor operators who may not need an extensive understanding of physics and mathematics when dealing with the rule-heavy Mamdani Fuzzy Controller (if this..., then that...), at a more advanced academic level, we aim to design the elegant and minimalistic Sugeno Fuzzy Controller. This task aligns with the work of scientists, technologists, engineers, and mathematicians (STEM).

I hope this feedback is helpful.

Thanks alot Sam for your help, but lastly how do I locate a Centrifugal compressor Block on simulink, I've been searching the entire library but can't find any

Hi @MADUKA CHIKA

I came across two Slimulink blocks for dynamic centrifugal compressors. One is specifically designed for gas compression, while the other is tailored for compressing two-phase fluids. You can find more information about them at the following links:
