Zhao Hong (Department of Mechanical and Electronical Engineering, Beijing University of Petroleum, Beijing,102249) Zhao Shengdun Zhou Mingyong Luo Chuangang Lin Tingqi (Department of Mechanical and Electronical Engineering, Xi'an Jiaotong University)  
A new computer control system for the control of the slide in a mechanical press to insure on a accurate positioning was proposed. The control system is made up of the pneumatic proportional valve, pneumatic friction clutch and brake, displacement sensor etc. The working process and control principle were analyzed and described. It is obvious that fuzzy control strategy is appropriate for use in the control system. Design of the fuzzy controller was given in details. Experiments were carried out in the mechanical press model JH23-63. The results reveal the effectiveness and usefulness of the algorithm.
