Abstract

The invention discloses a method for optimizing parameters of an overlap controller of an edge trimming circle shear. The method includes the following steps that (1) relevant parameters are determined according to practical problems; (2) N groups of initial proportion integration differentiation (PID) parameters are generated; (3) the PID parameters are evaluated; (4) each group of PID parameters are adjusted and processed; (5) the adjusted and processed PID parameters are evaluated to obtain the current optimum PID parameters; and (6) iteration is performed to obtain the optimum PID parameters, and the deviation of the overlap of the edge trimming circle shear is minimum. By means of the method, the parameters of the controller during control over the overlap of the edge trimming circle shear are obtained according to random arrangement, the parameters are optimized by a particle swarm algorithm to obtain the optimum controller parameters in the overlap of the edge trimming circle shear, and thereby the deviation of the overlap is minimum.

Description

technical field [0001] The invention belongs to the technical field of industrial control, uses a particle swarm algorithm to solve the parameter optimization problem of an overlap amount controller in edge trimming disc shears, and particularly relates to a parameter optimization method for an overlap amount controller in edge trimming disc shears. Background technique [0002] The control precision of the trimming disc shear has an important influence on the quality of the finished strip. If the precision does not meet the precision requirements of the shearing process, it will cause the problem of the quality of the strip and the deviation of the strip. Among the control problems of edge-cutting disc shears, the adjustment and control of the overlap is the most complicated. [0003] Under the premise of ensuring the control accuracy, most of the existing disc shears in China use AC motors and variable frequency speed control systems to realize the disc scissors disc contr...
