Abstract
Hardware In the Loop Simulation (HILS) system for seawater desalination plant was developed. This HILS system mounted simulation model of the plant on a digital signal processor (DSP). As real plant can be replaced by the DSP, we can adjust control equipment for the plant by using the DSP before the plant completion. In modeling of constituent equipment, characteristic curve was linearized locally for reducing analysis time, and analysis accuracy was improved by reducing time inclement. Simulated result from the developed HILS system was in good agreement with measured values of real plant.
