Analysis of the schematic diagram for feedforward-feedback composite control.
Thread Content
I would like to study the combustion control principles of the furnaces in sulfur plants. But this complex control has always been a weak point. I hope everyone can discuss and learn together*
It’s better to find a book on control principles and control engineering*; it’s not something that can be explained in just a few words.
It’s very complicated; I need to look up some information first. It will probably take dozens of floors to explain it clearly
This can’t be explained in just a word or two; you need to find a specialized book and read it carefully
I’m reading the book. As for this diagram, I’m not quite sure which part represents the feedforward and which part represents the feedback Seeking advice. . . . After all, practical application is more complex than what is written in books. .
Well, let’s talk about it then; it’ll help us all gain more knowledge, and good knowledge should be shared. . I’m not afraid of tall buildings; I’m afraid that they can’t be built. Hahaha
Feedforward-feedback isn’t that difficult either; the reason people can’t understand it is simply a lack of knowledge about the process. Without an understanding of the process, it’s impossible to carry out calculations, and naturally, it’s hard to grasp feedforward as well.
It’s quite complex; this diagram represents more than just simple feedforward-feedback control, as it also includes cascade control, which makes it complex.
The image cannot be opened, but forward control can be understood easily once it is analyzed properly. For example, in the case of a forward feedforward combination, this forward element is simply equivalent to a large disturbance that cannot be eliminated by the feedforward mechanism. Therefore, feedforward control was added to eliminate this disturbance
