Concept of Analog Flexible Fuzzy Control and its Application in Control System of Power Plant

The concept of analog flexible fuzzy control is introduced in this paper. It is applied in the boiler-turbine coordination control system and reheated temperature control system. The practical result shows that this algorithm is easy to be realized in project by applying all sorts of existing algorithms in computer system not depending on special fuzzy control module. This algorithm not only overcomes the large lag and inertia for boiler, but also can heighten the responding rate to AGC in boiler-turbine coordination control system effectively and reheated temperature control characteristic.
