Fuzzy Control of Electromagnetic Blank Holder System

Electromagnetic blank holder is an advanced manufacturing technology. Fuzzy control is used for electromagnetic blank holder control system in this paper. Firstly, the designed device of electromagnetic blank holder is introduced. The force of electromagnetic blank holder is analyzed and its formulas are deduced. The structure of force-current double closed loop control system is adopted. Strategy of fuzzy control of electromagnetic blank holder force is proposed. Design of fuzzy-PID controller is given. Finally, simulation models of electromagnetic blank holder fuzzy control system are established using Matlab/Simulink, Simplorer and Maxwell. By co-simulation, the results show that control system can get good dynamic and static performance using fuzzy-PID algorithm. The research results of this paper can promote the development of drawing technology of high precision metal sheet cylinder.
