Abstract
A method and apparatus of controlling a vibrating feeder applies a drive signal to a vibrating mechanism connected to the vibrating feeder at a first predetermined power level, and subsequently applies the drive signal to the vibrating mechanism at a second predetermined power level which is greater than zero and lower than the first predetermined power level whereby an amplitude of vibration of the vibrating feeder converges towards a target amplitude. Another method and apparatus of controlling a vibrating feeder applies a drive signal having a phase to a vibrating mechanism connected to the vibrating feeder at a first phase and subsequently applies the drive signal to the vibrating mechanism at a second phase which is different from the first phase, whereby an amplitude of vibration of the vibrating feeder converges towards a target amplitude.
