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.
