| Abstract: | Based on the nonlinear characteristic of three-phase voltage source PWM rectifiers,a nonlinear control strat-egy is proposed.The voltage and current controllers are designed by using active disturbance rejection control(ADRC) technique,and then,the controllers have the advantage of robustness.The load disturbance is compensated by the voltage controller,which effectively removes the static tracking error of the output direct current(DC) voltage,which is caused by the disturbance.The switching signals of the... |
