A system for generating acoustic ultrasonic vibration, with a generator for generating an alternating voltage (U) with a frequency f and converter for converting the alternating voltage into acoustic ultrasonic vibration, with a control device, which captures the vibration amplitude (Aist) of the ultrasonic vibration and compares said vibration amplitude with a desired vibration amplitude (Asoil) and changes a manipulated variable with the goal of bringing the captured vibration amplitude (Aist) closer to the desired vibration amplitude (Asoil). The generator has a frequency control module with a frequency control input. The frequency control module defines, in accordance with a signal present at the frequency control input, the frequency (f) of the alternating voltage (U) to be generated. A system which at least mitigates the mentioned disadvantages, allows higher processing speeds and associated abrupt load changes. A control apparatus converts an input signal into a manipulated signal, the desired vibration amplitude (Asoil) being provided as the input signal, and the manipulated signal being connected to the frequency control input.
A system for generating an ultrasonic acoustic vibration with a generator for generating an alternating electrical voltage U with a frequency f and a converter for converting the alternating electrical voltage into an ultrasonic acoustic vibration with a regulation device which detects the vibration amplitude Aist of the ultrasonic vibration and compares it with a desired vibration amplitude Asoil and changes a manipulated variable with the aim of approximating the detected vibration amplitude Aist to the desired vibration amplitude Asoil,
