Research On The Thermal Control Of Low Multiplying Power Circulating Fluidized-bed

Circulation fluidized bed combustion tec is a kind of high-efficient, clean coal combustion tec. This paper proceeds from circulation fluidized bed structure and operation mechanism, has explained controlling the task basically of the circulation fluidized bed. Circulation in boiler in fluidized bed each distribute by parameter, variable coupling close tightly, when become by target of controlling which not prolonging by non-linear one, because structure its very complicated, influence factor that its combustion. How to raise it combustion control system task of top priority。The artificial neural network has very strong information processing, memory and study the function by itself, but because its algorithm complicatedness, learning process are longer, the parameter disappears slowly etc. to make its application limited. This paper propose many variable neuron network controller, apply it circulation fluidized bed combustion control, make neural network and PID control law combine together , is it prolong to strong coupling multi-variable system is it solve coupling control to go on at the many variable to use for. Artificial result indicate multi-variable neuron network controller prolong to strong coupling multi-variable control system have good control results at the multi-variable control system.
