Disturbance observer based multiloop proportional feedback system for output voltage regulation in three phase AC to DC converters

Scientific Reports
This paper suggests a disturbance observer (DOB)-based offset-free output voltage regulator for the three-phase AC/DC power converters, taking the nonlinearity, parameter, and load uncertainties into account. The proposed multiloop controller is designed
