Embodiment Construction

[0024] In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only some embodiments of the present invention, rather than all embodiments of the present invention, and it should be understood that the present invention is not limited by the exemplary embodiments described here. Based on the embodiments of the present invention described in the present invention, all other embodiments obtained by those skilled in the art without creative effort shall fall within the protection scope of the present invention.

[0025] figure 1 It is a schematic diagram of fuzzy controller control. When controlling a variable, the purpose of control is to expect the actual value of the variable to be the same as the label value. The difference between the tag value and th...

Abstract

An embodiment of the present invention provides a method for fuzzy control of a control system, a fuzzy controller, and a computer storage medium. The method includes: performing fuzzy calculation of input variables to obtain the degree of membership of the input variables, wherein the input variables Including deviation and rate of change; based on the rule base expressed in matrix, according to the degree of membership of the input variables, the incentive intensity corresponding to each rule in the rule base is obtained; the output variable MF of the rule corresponding to the incentive intensity is calculated by using the incentive intensity Cut to get the corresponding output MF; combine the output MF corresponding to all the rules to get the total output MF. It can be seen that the fuzzy control method in the embodiment of the present invention uses a matrix-based rule base to carry out the fuzzy reasoning process. This process can break away from the original PLC framework, is suitable for general operating systems, and can be performed in a high-level language. And the general algorithm can be easily extended to other application fields.

Description

technical field [0001] The invention relates to the field of process control, and more specifically relates to a fuzzy control method, a fuzzy controller and a computer storage medium. Background technique [0002] In the control of waste combustion process, due to various reasons such as environment and raw materials, many production processes cannot accurately establish a model control system. This kind of problem cannot be solved by a traditional proportional-integral-derivative (PID) control system, and various model-based control systems are useless. Contents of the invention [0003] The present invention has been made in consideration of the above-mentioned problems. The invention provides a fuzzy control method for a control system, a fuzzy controller and a computer storage medium, which are suitable for general operating systems and can be extended to various other application fields. [0004] According to a first aspect of the present invention, there is provid...
