Abstract: According to the mathematical model of natural gas flow, a flow control system was proposed based on information fusion and cluster analysis. The system consists of an ART-2 network and a BP network. Pressure differences, pressures and temperatures obtained by sensors are fused and the output spaces are controled according to cluster control strategy. This system has been used in a romote monitering and control system. The operation of the system shows that the pressure fluctuation is controled within 10% when the range of the natural gas flow is between 5% and 95 % of the maximum flow.
