1. A method for controlling a body for compacting material comprising the steps of:

  • exciting the body to give the body an oscillation movement, the excitation being periodic and having a frequency;

    sensing said oscillation movement; and

    controlling the exciting step, so that the resulting oscillating frequency of the vibrating body contains a predetermined proportion of a harmonic oscillation having a frequency corresponding to half the frequency with which the body is excited, thereby avoiding undesired oscillation movement.
