To solve the problem of traditional electromagnetic quantitative feeding system in the process of the open loop control the feeding speed setting arbitrary large, not according to the intelligent control strategy for dynamic adjust the feeding speed, a quantitative electromagnetic vibration feeder was designed based on fuzzy PID control system. Taking the mechanical structure design of the system as a whole, the conduction angle of silicon controlled rectifier was obtained by theoretical analysis and mathematical relationship between amplitude, and according to this, the simplified mathematical model of electromagnetic vibration feeder second order was established. The simulation results show that the system has good dynamic, high control precision, high response speed and higher robustness, and also has good application prospect.
