This is an example package of modeling a controller for the Single Board Heater System (SBHS) system using the Modelica_DeviceDrivers AVR package.
SBHS is a lab-in-a-box setup useful for teaching and learning control systems. It consists of a heater assembly, fan, temperature sensor, ATmega16 micro-controller and associated circuitry. A stainless steel blade whose temperature has to be controlled serves as the plant. Nichrome helical coil with 20 turns kept at a small distance from the steel blade, acts as the heater element. AD590, a monolithic integrated circuit temperature transducer, is soldered beneath the steel plate. A computer fan, a low cost and commercially of the shelf component, is used to cool the plate from below.
