Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The method of the present invention aims to learn from the optimization idea of ​​brainstorming, aiming at the mathematical model between the change of overlapping amount and the rotation angle of the eccentric sleeve, to solve the control problem of cutting edge disc shears in the field of industrial control, and to use the brainstorming idea to control the disc shears. The controller parameters of shear overlap are optimized and adjusted to solve the quality problems caused by some bad cutting that may occur when the disc shears trim the steel plate.

[0034] The brainstorm-based parameter optimization method of the disk shear overlap controller in the present invention is specifically implemented according to the following steps:

[0035] Step 1: Establish a mathematical model for parameter control of the overlap amount

Abstract

The invention discloses a circle shear overlap amount controller parameter optimizing method based on brainstorming. The method comprises the steps that 1, a mathematical model controlled by overlap amount parameters is set up; 2, relevant parameters of practical problems and brainstorming optimizing strategies are set; 3, N sets of initial PID control model parameters are generated; 4, the PID parameters are evaluated; 5, PID parameter sets are updated on the basis of the brainstorming optimizing idea, and clustering, selecting and mutating are carried out on the PID parameters; 6, whether updating of all PID parameter individuals is finished is judged; 7, whether the number of iteration times t reaches the maximum number of iteration times is judged. The method is simple in step and accurate in control.

Description

technical field [0001] The invention belongs to the technical field of intelligent control of mechanical equipment, and relates to a brainstorm-based parameter optimization method for a disc shear overlap controller. Background technique [0002] The quality of the finished strip has a significant impact on the production efficiency of the enterprise. In the strip steel production line, the control accuracy of the trimming disc shears is the key factor to improve the quality of the strip. Low precision will cause the quality of the trimming of the strip to change. Poor and strip deviation problems. [0003] The adjustment of the overlapping amount of foreign high-end slitting disc shears is also mostly manually operated, and the adjustment mechanism is generally arranged on the operating side of the equipment. Sex has a negative impact. [0004] Most of the existing technologies in China use traditional PID to control the AC motor and frequency conversion speed regulation ...
