Repetitive controller to compensate for (61+-1) harmonics
(2015-04)
"A repetitive controller scheme with two feedbacks one negative and one positive plus a negative feedforward introduces infinitely many poles on the imaginary axis located at j(6l+-1)omegao (l=0,1,2, . . . ,[infinity]) ...
Repetitive controller to compensate for odd harmonics
(2016-12)
"A repetitive controller scheme with negative feedback and feedforward introduces infinitely many poles on the imaginary axis located at the resonant peaks. The feedforward introduces zeros, which produce notches located ...
Controller for the three-phase cascade multilevel converter used as shunt active filter in unbalanced operation with guaranteed capacitors voltages balance
(2013-02)
"The present invention comprises a controller for the cascade H-bridge three-phase multilevel converter used as a shunt active filter. Based on the proposed mathematical model, the controller is designed to compensate ...
Fixed reference frame phase-locked loop (FRF-PLL) for unbalanced line voltage conditions
(2008-10)
"The present invention relates to a system to implement a phase-locked loop (PLL) which is able to provide an estimation of the angular frequency, and both the positive and negative sequences of the fundamental component ...
Repetitive controller for compensation of periodic signal
(2016-12)
"A repetitive controller scheme with positive feedback and feedforward introduces infinitely many poles on the imaginary axis located at the resonant peaks. The feedforward introduces zeros, which produce notches located ...
