This paper presents a spreadsheet method for the graphical simulation of analog computers (AC) used in control systems. It is based on simulating basic AC blocks like adders, integrators, potentiometers, inverters, and nonlinear devices. To make the simulation simple and user friendly, the construction of an AC system is done graphically, whereby blocks are(More)
This paper presents a model for a hydrogen production fuel station, which simulates the complete process of hydrogen production under different conditions and demands. This simulation entails the modeling of four main components: an electrochemical hydrogen production cell with a thermal model, electrochemical compression and storage, and optimal car(More)
