In-circuit simulation of industrial processes with personal computers

The principle of in-circuit simulation, with PCs is described and shown for two cases. In the first case, for oil-fired central heating with low power (<120 kW), the boiler- and the heat-temperature-control of the heating system are presented. The house and the heating system were simulated on a PC. In the second case, the combustion control of a medium-sized industrial boiler (20 MW) is presented. The combustion was simulated on a PC and the combustion control was accomplished by the MMC-90 microcomputer-based multiloop controller.<
