Problems solved by technology

However, the F.C. meter also has shortcomings, such as inconvenient self-adjustment and self-correction, and sometimes there are shortcomings such as fluctuations in output level values.
In order to solve these shortcomings, Professor Wang Peizhuang proposed to use the F.C. analytical formula to replace the F.C. table. The F.C. analytical formula is convenient for optimization, but the simple analytical formula cannot describe all complex control objects

Abstract

The invention discloses a fuzzy control method for a kiln thermal parameter control system. According to the fuzzy control method, a fuzzy control rule list is partitioned according to the control characteristics of the system, and different sections are described through different analytical expressions. The fuzzy control method is used for controlling various kiln thermal parameters, has the good control effect and is simple in operation and quite high in application and popularization value.

Description

technical field [0001] The invention belongs to the field of thermal process automatic control, and in particular relates to a fuzzy control method used in a kiln thermal parameter control system. Background technique [0002] In the control system, the fuzzy control (F.C.) table reflects the fuzzy language control experience summed up in practice to describe the relationship between various factors, because it does not require precise mathematical models, it is suitable for linear and nonlinear , time-varying and lagging system control, which has been widely used. However, the F.C. meter also has shortcomings, such as inconvenient self-adjustment and self-correction, and sometimes there are shortcomings such as fluctuations in output level values. In order to solve these shortcomings, Professor Wang Peizhuang proposed to use the F.C. analytical formula to replace the F.C. table. The F.C. analytical formula is convenient for optimization, but the simple analytical formula c...
