Fuzzy Self-tuning PID Parameter Control Of Hydraulic Crane Based On Kingview SoftWare

In the field of hydraulic system, the purpose of crane is very popular and abroad, especially in port and on ship. In a word, the crane is closely related to people, and this means it is significant to people.At present, the workers operate crane by hand in our country, and manipulate crane through their experience. This increases ratio of lapsus and decreases work efficiency. The laggard monitor and control and management mechanism can't suit to the request of the yield and development of science and technology. Today, precision, convenience, and Real-time control become the developing trend of hydraulic fluid intelligent control, along with the progress of intelligent control.The system constructs DY200010-00 hydraulic crane at research and exploits center of outfit product of shipping mechtronic of Dalian Maritime University into a monitor and control system of computer, through adopting survey and control system of computer on the basis of configuration soft of industry automatization, combining with sensor technic, Matlab Simulink technic and surveying and measuring technic of computer,.The crane model can't be founded exactly because of the enormous changes of conditions such as temperature and pressure and other interfere factors. So the advantage of hydraulic intelligent control system, that is, exactness and economy can be exhibited furthest only by designing control system rationally and effectively. This system realizes control of hydraulic system through fuzzy self-tuning PID parameter on-line, increasing adaptability of the system to uncertain factor, and finally acquiring the ideal effect. The approach is compiling controls arithmetic and controls procedure, emulating with computer through the simulink tool of Matlab soft, and realizing Real-time monitor and control by the Kingview configuration soft.This system has many function such as collecting signal, analyzing trends, analyzing forecast, assisting and helping system, also it can execute dynamicmanagement of supervisory parameter, create report forms automatically, run at random, and it can be rectified and expanded easily.The system realizes Real-time monitor and survey and dynamic management, and it improves the level of monitor and control of hydraulic crane.
