Water Level Control of After Condenser in a Spray Flash Desalination System Using Stochastic Process

抄録

In this paper, water level control of after condenser in a spray flash desalination system is considered. First, a mathematical model of the water level is constructed based on mass conservation law and thermophysical property. Secondly, control system using PI controller and some characteristics concerning the valve is designed. A simulation result by using the control system shows that the behavior of an experimental result is not captured appropriately. In order to tackle this problem,in this paper, another water level model is proposed by introducing a white Gaussian process. The effectiveness of the control system with proposed model is verified through simulation results.
