Abstract: In order to improve the motion speed and operational efficiency of the eight bar stamping mechanism, a motion control method based on fuzzy self-tuning PID for the eight bar stamping mechanism is proposed. Firstly, based on the structural principle of the eight bar stamping mechanism, a dynamic model of the eight bar stamping mechanism is constructed by combining collision contact force and friction force, and its motion characteristics are analysed. Secondly, a fuzzy self-tuning PID controller structure is designed and the basic and fuzzy domains of the controller output and output variables are set. Finally, by setting fuzzy rules, self-tuning parameters are calculated. The parameters are input into the controller to complete the motion control of the eight bar stamping mechanism. The experimental results show that the method proposed in this paper can improve the operational efficiency of the eight bar stamping mechanism while increasing its motion speed.
Keywords: fuzzy self-tuning PID; eight bar stamping mechanism; motion control; fuzzy rules.
