Abstract

The invention relates to a genetic optimal controlling technology of a piler, which is used for performing speed optimization control on the operation process of a piler by means of a neutral network and a genetic algorithm so as to reduce vibration produced in the high-speed operation process of the piler. A neutral network mapping model between the vibration state of the piler and main operating parameters is created on the basis of the main operating parameters in the operation process of the piler, and vibration data produced in the operation process of the piler are used; the operating speed optimization for minimum vibration in the operating process of the piler is carried out on the basis of the created neutral network mapping model by using the genetic algorithm; and an operating speed control curve of the piler is obtained on the basis of the piler operating speed obtained through optimization, and the speed control on the piler is realized by using the numeric conversion of a programmable logic controller and a variable-frequency controller.

Description

Technical field: [0001] The invention belongs to the related field of stacker control, in particular to a genetic optimization control technology for the operation process of the stacker. technical background: [0002] Because the automated three-dimensional warehouse has the advantages of high space utilization rate and high degree of automation, its application range is becoming wider and wider. As the stacker crane, the key equipment in the three-dimensional warehouse, its control technology is very critical to the performance of the stacker crane. With the wide application of programmable logic controller (PLC), frequency conversion speed regulation, laser ranging and other technologies in the field of stacker control, the operating speed of the stacker has been significantly improved. However, the increase in the operating speed of the stacker has brought problems such as vibration, so it is necessary to optimize the speed of the stacker during operation to reduce the ...
