This paper studies the closed-loop control of an electromagnetic vibratory feeder (EVF). Two different linear design procedures have been employed: a conventional proportional-integral-derivative (PID) controller, and a model predictive control (MPC) controller.The Electromagnetic Vibrating Feeder. The vibrating feeder has been around for quite some time and the technology has changed little from the original designs created several decades ago. The theory behind the feeder is that the vibrating action of the feeder arranges a product into the correct rotation or amount necessary for a process or the next stage of manufacturing.

Feeder Control. The electrical controllers for our electromagnetic feeders are designed around half-wave rectification of AC power. The efficient switching mechanism of silicon controlled rectifiers produces DC impulses without wasteful resistor or rheostat energy loss. Plus, it provides a full 0 – 100% range of control.An electromagnetic-type vibratory feeder of is a typical transportation device used in automatic weighers. As existing feeders are driven by feedforward control, the so-called “firing angle control”, the driver cannot negate sudden disturbances. In this study, we consider applying a feedback control for such a feeder system. First, we give the two details of modelings for the vibration ...
Electromagnetic vibratory feeders are commonly used for mining and quarry operations, as well as aggregate, chemical and industrial processes. Jeffrey Rader electromagnetic feeders operate through controlled, high-frequency vibration. This is accomplished with electrical pulses and sub-resonant tuning. With their unique low-maintenance design ...The electromagnetic feeders give greater control over the product, providing either a continuous feed, or a feed that can be regularly stopped and started for a more measured throughput. These feeders are generally used for applications that demand careful handling, such as in food processing environments.
