PolFEL will be Free Electron Laser based on the 200 MeV linear superconducting electron accelerator made of the TESLA type cavities, targeting VUV, IR and THZ wavelengths. Described accelerator will be able to operate in the pulsed wave (PW) mode, but the main operational mode will be continuous wave (CW). PolFEL will operate in the single cavity regulation mode using solid state amplifiers - one per RF structure. Custom and flexible LLRF system will be needed to achieve goals described above. This contribution will present concept of the LLRF system for PolFEL, proposed technologies and techniques, and results of the first successful closed loop operation, performed in the laboratory with the prototype system and copper cavity.
