Abstract
As engineering systems become more and more advanced, the need for collaboration and communication between dierent system areas increases. Systems Modeling Language (SysML) is a graphical modeling language developed to provide a modeling capability independent of the system area. In this thesis, a SysML model will be developed for a reverse osmosis water purication plant. The purpose of the model is to document requirements stated by stakeholders and to use these requirements as a basis for the development of a new control system. The control system developed is composed of several state machines, with each state machine controlling its own part of the plant. Also, as the reverse osmosis plant wastes a lot of water, a control strategy is... (More)

The control system developed is composed of several state machines, with each state machine controlling its own part of the plant. Also, as the reverse osmosis plant wastes a lot of water, a control strategy is developed in order to feed otherwise wasted water back into the system. The validation of the control strategy is done against a mathematical model of the membrane process, which is also derived. First the control system is simulate using Matlab/Simulink and later implemented in C code on a PLC. (Less)
