Novel proportional-integral-resonant current controller for three phase PWM converters

摘要

In this paper a novel current control algorithm for a pulsewidth modulation (PWM) voltage-source converters is proposed, based on the reduced order generalized integrator (ROGI). Namely, existing ROGI based algorithms include proportional (P) and resonant (R) control action, while the integral (I) action was not, so far, combined with ROGI. Furthermore, since proportional-integral-resonant (PIR) controllers are employed in control of various three-phase PWM converters, in this paper the P-ROGI controller is combined with an integral control action in order to enable its use in the same field of application as PIR. Consequently, the novel PI-ROGI control algorithm is presented in the paper, and implemented in AC current control of a three phase PWM rectifier. The novel controller performance is verified by means of simulation.
