Using Smalltalk for a Heat Control System

Typically, commercially available Heat Control Systems use temperature hysterisis for the control of a heating system. I show an example of a heat flow controled system based on USB-Data Acquisition hardware and self-made sensor- and actor-hardware.

The control is fully done in VisualWorks, which gives phantastic flexibility for reaching nice control behavior. For testing the whole system, a simulator has been developed which helped a lot, avoiding bad problems when starting with the real heating. The simulator in action and some photos will be shown, to give a feeling of the whole endeavor.
