Human intuition reasoning type fuzzy controller

Abstract

The invention relates to a human intuition reasoning type fuzzy controller, composed of a data input unit, a preset storage unit, a deviation data channel, a deviation change rate data channel, a data selection unit and a data output unit; wherein the data input unit receives an external signal and outputs a deviation signal and a deviation change rate signal, the deviation signal output terminalof the data input unit and the preset storage unit are connected with the input terminal of the deviation data channel, and the deviation change rate signal output terminal and the preset storage unit are connected with the input terminal of the deviation change rate data channel, the preset storage unit stores a group of preset numerical value in fuzzy theory domain, the data selection unit selects the preset numerical value in the preset storage unit according to gating signals respectively output by the deviation data channel and the deviation change rate data channel and outputs the preset numerical value by virtue of the data output unit. The invention has the advantages of simple structure, low cost, low overhead, less transmission delay, fast processing speed, being user-friendly and being stable and reliable.

Description

technical field [0001] The invention relates to the technical field of fuzzy control, in particular to a human-like intuition reasoning fuzzy controller based on conventional logic devices. Background technique [0002] As we all know, the fuzzy controller is an intelligent controller based on language rules, which has been used in various industrial process control and home appliance control fields, but the design of the fuzzy controller has a high technical threshold for the designer, thus limiting it. Further promotion and application. Since the generation of the fuzzy controller, the most direct motivation for people to apply it comes from: some production sites have many successful manual operation experiences, which can be written in the form of IF-THEN language rules, and people hope to use the control device to replicate the human brain. control behavior. However, human language is ambiguous, and control devices are based on specific values, which has become the bi...

Problems solved by technology

[0005] ①Based on the control circuit of CPU and memory, the reasoning method is written as program instructions and burned into the memory chip. The advantage of this form is that the software programming is flexible, but the disadvantage is that the processing speed is slow and the stability is poor

[0006] ② Based on the memory control circuit, the mapping relationship of all input and output data is directly stored in the memory chip in advance. The advantage of this form is that the processing speed is relatively fast, and the disadvantage is that the flexibility is poor

[0007] The common disadvantage of both is that they both need to use abstract and difficult-to-understand fuzzy reasoning methods, which are difficult to learn and use. This poses a challenge to many front-line engineers and restricts the promotion and application of fuzzy controllers.
