摘要：
The process state of iron ore sintering is characterised via the bed permeability, the temperature rising point, the burn rising point and the burn through point. The intelligent control strategy of sintering process based on fan frequency conversion is put forward. The stability of process state is firstly evaluated based on the knowledge of domain experts. If process state is fluctuating, an expert controller is activated to realise a normal production. If process state becomes steady, then a fuzzy controller is activated to obtain the optimisation of process state and reduce the power consumption of main exhaust fan. The closed-loop control of sintering production showed that the system can realise the optimisation of sintering process state, and reduce the energy consumption of sintering production while ensure the stability of sinter quality indices, it theoretically saves power consumption of 1x10(4) kWh every day.
