Abstract :
FPGA technologies realize very fast digital calculation capability with 1MHz order data sampling feedback in power electronics field. A new approach of precise digital control method of 1MHz variable multi sampling deadbeat control combined with multi-rate control method using FPGA based hardware controller is proposed. Applying three kinds of discrete time model, PWM pulse width is recalculating every 1μ second while the carrier interval based on multi-rate deadbeat control. A good transient response and robustness can be realized. Through simulations and experiments, verification is carried out and compared with other digital control approaches.
