Model-Free Sliding Mode and Fuzzy Controllers for Reverse Osmosis Desalination Plants
This paper presents model-free sliding mode controllers and Takagi-Sugeno fuzzy controllers for the flux and conductivity control of Reverse Osmosis Desalination Plants (RODPs). The RODPs are Multi Input-Multi Output processes and two separate controllers are designed in Single Input-Single Output control systems. The design of the model-free sliding mode controllers is done by Lyapunov’s stability theory. The Takagi-Sugeno fuzzy controllers are designed by considering linear matrix inequalities as constraints in an optimization problem solved by a Grey Wolf Optimizer algorithm. Simulation results are included.
Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
