Research Of Files Carousel Controls System Base On Fuzzy Control For Position Technique

Automation files carousel is a new kind of files storage device,and has great social and economic value.Whereas traditional files storage is in the manner of manpower to store files in the cabinets.This caused inefficient,not easy to find files.In recent years,with automatic storage containers gradually popular in China,developing a new file storage container has become an urgent affair.And it can be storage real-time and automatic to deposit or remove files,and can share with the files database management system.With the applying of the automation files carousel for files storage management,many government agencies and institutions improve the management level of informationization.The control system of automation files carousel is the core of operation.The positioning accuracy of box of the files carousel affects the system operation efficiency.This subject study and design for the control system of automation files carousel,and it adopted Siemens S7-200 CPU 226 as control core to design for the control system of automation files carousel, to realize loading and unloading function of files,and realize function of the automatic stocktaking carousel.According to the operating principle of the control system of the files carousel,this subject puts forward the strategy of the hardware design of System and the PLC control procedures,and designs the hardware circuit and the corresponding software.In positioning method,choose positioning method of the rotary encoder to determine the position of a box when the system is running.In the comparison for position technique of automatic warehousing system,study and design based on fuzzy control technology.With the position error and its error rate as input,system are made in many modifying factors of the fuzzy control rules from the adjustment method,and design of fuzzy controller.Experimental results show that the positioning technology orientation effect of the fuzzy control technology superior currently popular technology of automation files carousel.In parts of dynamic property and static properties and anti-disturbing capability has the very big enhancement.So it is essential and tolerable for this controller to apply to orientation controlling of the files carousel.
