Abstract :
The digital control systems use the ADCs/DACs as a front-end for analogue signals processing. The paper proposes the solution to enhance the DAC resolution by PWM. The modulation scheme is optimized to the parameters of of LLRF control in FLASH accelerator. For that purpose the genetic algorithm was implemented and applied. The distributed computing was used to speed-up the computations.
