Abstract : In this contribution, the control of Reverse Osmosis (RO) desalination plant using PID controllers is presented. The tuning of PID controllers is accomplished by minimizing the Integral-Square-Error (ISE). The ISEs are minimized using the Luus–Jaakola (LJ) optimization algorithm. LJ procedure is simple, yet powerful method, available in literature. In this approach, first the feed forward controllers are designed and then the PID controllers are tuned for pH and conductivity using ISE minimization. For the simulation purpose, the DOHA reverse osmosis plant is considered. The results of PID control using LJ method are compared with the Ziegler-Nichol’s (ZN) tuning. The simulation results show that the LJ method performs better than the ZN technique and can successfully be used for tuning of PID controllers for RO desalination plant. Keywords- Luus–Jaakola(LJ) optimization, Reverse osmosis (RO), ISE, PID tuning.
