Abstract
In the previous paper, we developed and analyzed the computer simulation model of the CELSS. We also proposed and evaluated its control method which defines control inputs based on fuzzy linear programming. In order to develop more reliable system, the, detailed analysis of the system components is required. In this paper, we developed three different systems; (1) the system with a fuel cell, (2) the system without a tank of hygiene water, and (3) the system without an electrolysis tank. From the result of dynamic computer simulation, the behavior of these systems was evaluated in comparison with the system developed in the previous paper.
