Análise e implementação de retificadores PWM trifásicos com resposta de tempo mínimo utilizando desacoplamento por retroação de estados

Abstract: This paper develops a systematic design procedure based on discrete decoupling by state feedback applied to three-phase PWM rectifiers. A discrete model for synchronous frame is developed for three-phase PWM rectifier with an L filter. This model takes into account the computational delays presents in the discrete implementation. Deadbeat response is obtaining without the requirement of a current controller in the axis d. Moreover, discrete servo controllers to ensure unit displacement power factor and regulat… Show more

“…As usually the PWM converters are analyzed and controlled considering phase quantities [18,19], the line-to-line voltages vector, v l-l , is transformed into a phase voltage vector, v ph . This transformation is not unique, so, it will be assumed that the sum of the phase voltages is zero.…”
