【正文】 factors such as disturbance and outside, the paper will be fuzzy control and PI control of bining the design of the fuzzy selftuning PI controller, and gives a fuzzy control lookup paper is received by the basic structure and engineering system. It introduce the production of Siemens SIMOREG DC Master 6RA70 fully digital DC converter and designs the device startup steps and parameter settings at first. Second, it designs the remote monitoring system, greatly facilitate and simplify control of the towing operation. Finally, through the EMC design of the fully digital DC converter control system, improving the system’s antijamming , through digital simulation of the system that under the control of the conventional PI controller and fuzzy selftuning PI controller under, gives the test results waveform of the system debugging operation the at the scene .After a period of trial operation of the system ,proving that works well and achieves the desired objective of the design The application of lifting equipment in industrial is extremely universal, and hydraulic motors or hydraulic cylinder controlled by electrichydraulic proportional valve or electrohydraulic servo valve often used as its power sector. With motor or cylinder controlled by valve to achieve up or down and speed control. Electrohydraulic proportional control and electrohydraulic servo control need high investment costs, high maintenance requirements. And during the lifting process, there is speed error and vibration phenomenon which affects the normal production. In order to satisfy production requirements and improve production efficiency, it needs to research a new control method to pensate for these the rapid development of science and technology, the application of puter technology in the hydraulic field promotes generation and development of the digital electrohydraulic control technology, and also makes digitization of hydraulic ponents bee an inev
