ABSTRACT:
In this paper, a high performance feedback controller for electromagnetic vibratory feeder is proposed. Electromagnetic actuator is driven by the switching circuit with pulse width as control variable. The controller structure consists of a PI controller combined with the state observer. The controlled variable is the resonant frequency vibration amplitude obtained in real time from the state observer. Use of the state observer allows fast disturbance rejection and reference tracking in both directions (amplitude increase and decrease). Simulations and experimental results from the real device are presented.
