Modeling and Feedback Control for Electromagnetic Vibratory Feeder The electromagnetic vibratory feeder is a typical transport device used on production lines. Existing feeders are driven by feed-forward control, firing angle control of the driver cannot cancel sudden disturbances. We applied feedback control to such a feeder, proposing 2 detailed models – a dynamic model for a vibratory mechanical element useful to mechanical design and another for an electromagnetic actuating element. Taylor's expansion of these 2 models yields a linear dynamic model useful in feedback control theory. The feasibility of the model was confirmed through simulation. In a preliminary experiment, we applied PI control to the feeder because the driver is nonlinear, and results confirmed that PI control improves transport of the feeder.
