    This work describes the design, development and application of the system for frequency control of EMMA accelerator radiofrequency cavity. The problem with the radiofrequency cavities is, that because of various factors (change in the environmental temperature, mechanical stress, ...), they are continuously frequency detuning. The consequence of the frequency detuning is that electromagnetic field in the cavity is not optimal for the acceleration of the particles. For this reason the resonant frequency of the cavities must be controlled so that it remains stable and as close to the nominal as possible. Because the above-mentioned factors are slow the problem can be solved with a slow control loop. For the acquisition of the radiofrequency signals, their analysis, control loop and the controlling of the stepper motors I have used instrument Libera LLRF from the company Instrumentation Technologies d.d.
