Method for generating loops based on water and wind command of unit load command

The invention discloses a method for generating loops based on a water and wind command of a unit load command. The method includes the steps that the unit load command obtains corresponding boiler command initial values through a polygonal function f(x) and then forms the three loops, namely the first loop including the unit load command, a polygonal function f11(x), a water feeding amount command initial value and a water feeding control system; the second loop including the unit load command, a polygonal function f12(x), a primary wind pressure command initial value and a primary wind pressure control system; and the third loop including the unit load command, a polygonal function f13(x), a wind amount command initial value and a wind feeding control system. By means of the method, thecoal feeding amount, water feeding amount and wind feeding amount of a boiler can be accurately controlled, the operation efficiency of a unit is improved, and safety and economy of the unit are improved. 本发明公开了种基于机组负荷指令的水、风指
