Problems solved by technology

[0005] The purpose of the present invention is to provide a method for adjusting parameters of disc shear overlap based on multi-objective brainstorming, which solves the difficulty in optimizing and adjusting the parameter adjustment of edge trimming disc shear overlap control in the prior art, resulting in disc shears in the opposite direction. Some bad cuts that may occur when the steel plate is trimmed affect the quality of the product

Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The method of the present invention aims at using the mathematical model between the change of the overlap amount and the rotation angle of the eccentric sleeve, adopts the idea of ​​brainstorming, regards the controller design of the overlap amount as a multi-objective optimization problem, and provides the parameters of the overlap amount controller Adjust strategy.

[0036] The present invention is based on the multi-objective brainstorming disc shear overlap parameter adjustment method, implemented according to the following steps:

[0037] Step 1: Establish a mathematical model for parameter control of the overlap amount

[0038] Such as figure 1 , the mathematical model controlled by the overlap parameter is:

[0039] δ=Φ-H2Rcosα, (1)

[0040] Among them, δ is the amount of overlap, Φ is the diameter of the outer circle of th...

Abstract

The invention discloses a method for adjusting overlap parameters of a cycle shear based on multi-target brainstorming. The method comprises the steps of 1, constructing a mathematical model for controlling the overlap parameters; 2, setting related parameters of actual problems and multi-target brainstorming optimizing strategy; 3, generating N groups of initial PID parameters; 4, estimating the PID parameters; 5, updating the PID parameter set based on the brainstorming optimizing concept; 6, determining whether all PID parameters are updated; 7, updating a non-dominated PID parameter solution set in an external filing set; 8, enabling the iteration times to reach the maximum iteration times, so as to finish the adjusting. The method is simple in steps and accurate in control result.

Description

technical field [0001] The invention belongs to the technical field of control, and relates to a multi-objective brainstorming-based method for adjusting parameters of disc shear overlap. Background technique [0002] In the strip steel production line, the control accuracy of the trimming disc shears is the key factor to improve the strip quality. If the precision is too low, the trimming quality of the strip will deteriorate and the strip will deviate. [0003] The adjustment of the overlapping amount of high-end slitting disc shears in foreign countries is mostly manually operated, and the adjustment mechanism is generally arranged on the operating side of the equipment. This method can ensure the consistency of the adjustment of the overlapping amount of the left and right racks and the scientific nature of the equipment structure. brought about a large negative impact. [0004] Most of the existing technologies in China use traditional PID to control the AC motor and ...
