In this paper, different strategies are investigated for the digital control of a reverse osmosis (RO) plant. Three control strategies to improve the performance of the RO plant are considered. These strategies including state-feeback, observer-based feedback and tracking control are considered. Simulation results show that the tracking controller yields the best perfoamnce, however it requires field knowledge about the RO plant operation. In this regard, observer-based feedback controller provides an alternative compromise.
