| Abstract: | This paper introduces an application of SIEMENS S7-300/400 PLC in the control of an experimental electric-heated boiler. The system is a two-layer network based on the industrial Ethernet and Fieldbus. The lab set can be used for the process control experiment, the coupling control experiment, the fuzzy control experiment and the neural network experiment. An algorithm of PID with the BP Neural Network is also introduced. |
