Problems solved by technology

Second, the batching from the batching room to the mixed material trough is actually a mixing and pelletizing process carried out by belt transmission and AC motor drive, which has a large time lag
However, in the variable structure control of the material balance system combined with the mathematical model and reasoning rules, the fuzzy control technology directly affects the change of air permeability due to the change of the material level of the mixture mine tank, making it difficult to realize the online operation of the model.

Embodiment approach

[0096] A major feature of material balance systems is hysteresis. Due to the existence of hysteresis, the difficulty of automatic control increases. In the actual situation that the lag of 16 minutes is much greater than the adjustable amount of 3 minutes, the present invention adopts the combination of classical control and fuzzy control, and consists of rule base 1, expert system 2, discriminator 3, monitoring system 4, and neural network. Recognizer 5, transfer function f(ρ)6 of the mixed material ore bin, process II7, controller II8, process e -τs I9, controller I10, distribution ratio 11 and ratio coefficient 12, among which, classical control realizes automatic batching and sequential control of 80 electrical equipment; fuzzy control forms corresponding membership functions and control rules based on operator experience, control rules and membership functions It can be adaptively optimized according to the dynamic changes of the process.

[0097] The control strategy o...

Abstract

Said balanced system adopts classical control and intelligent control combination, fully utilizing intelligent control technology to individually control every subsystem. At the same time, it utilizes mixed material hopper in and out quantity balance and level of material set value position tracking system to ensure whole large system stabilizing. In said invented material balance intelligent control, classical control realizes automatic proportioning and 80 electrical equipments sequential control; fuzzy control, according to operator experience, to form relevant membership function and control law which can realizes adaptive optimization according to procedural dynamic variation.

Description

technical field [0001] The invention relates to a material balance system in a complex batching process, which adopts the method of combining classical control and intelligent control to automatically adjust the ratio coefficient and batching ratio, so as to ensure that the system can effectively control the feeding amount of each raw material according to certain process parameters; at the same time, it can ensure The material balance on the entire loading line belongs to the automatic control technology of modern industrial large systems. Background technique [0002] In the material balance system, after the preparation of the raw materials is completed, in the batching room, the prepared raw materials are batched according to the process requirements, and the six raw materials are batched according to different ratio coefficients and distribution ratios. Put it into the sintering machine. The characteristics of the system control are: first, the cascade adjustment of th...
