A vibratory feeder of electromagnetic type is a typical transportation device used in automatic weighing processes. As existing feeders are driven by feedforward control so-called a "firing angle control", the driver can not cancel the effect of sudden disturbances. In this paper, we consider how to apply a feedback control to such a feeder system with the standard trough. First, we introduce a 2-degree-of-freedom PID controller to the feeder system. Next, it is confirmed through experiment to improve the transportation capability and the transient responsibility of the feeder system by using 2 d. O. f. PID control. Finally, we also propose the feedback system when parameters of the feeder system have been changed by using other troughs.
