This paper proposes a new control system that facilitates two-degrees-of-freedom (2DOF) control to reduce the output voltage distortion in the self-sustained operation mode of a photovoltaic generation system. The proposed control system is configured by combining the disturbance observer using a notch filter (notch type disturbance observer) and a sinusoidal tracking controller. This configuration of the system facilitates high tracking performance and high disturbance suppression performance. This system is a new frequency-separation-type 2DOF control system that has the complete tracking performance of only the fundamental frequency, and has the desired recovery performance of the other harmonic frequency and the quick inserting load current. The numerical simulation results and experimental results confirm that the proposed control system reduces the output voltage distortion in an effective manner. Furthermore, the proposed control system is highly robust to the changes in the load.

“…The concept of incorporating (s 2 + ω v 2 ) into the current controller according to the internal model principle is also employed in the PIS controller of Iwaji, and likewise by Fukuda [15][16][17]. However, it must be noted that the configuration of internal-model current controller proposed by Shinnaka in Ref.…”

“…However, it must be noted that the configuration of internal-model current controller proposed by Shinnaka in Ref. 18 is different from those proposed by Iwaji and Fukuda [15][16][17][18]. Unlike the internal-model current controller proposed by Shinnaka, the PIS controller does not support arbitrary pole placement for the feedback control system because of structural limitations [15][16][17].…”

“…When the configuration of the current controller is determined, it is important to set the controller's coefficients. In the PIS controller, the coefficients are found by using heuristic algorithms [16,17]. On the other hand, in the internal-model current controller of Shinnaka adopted in this study, simple analytic design of the coefficients based on stability theory is possible [18].…”

SUMMARYThis paper proposes and analyzes a new simple realtime phase-estimation method for single-phase signals, which is based on a vector mapping theory of n-dimensional to 2-dimensional vectors. According to the analyses, the proposed mapping method can estimate instantly and properly the true phase of the signals that are contaminated by significant amplitude of noise and harmonics. The mapping method contains the conventional DFT method as a special case. In other words, it can be treated as a generalization of the DFT. Several simple realizations of the mapping method are also newly proposed as a single-input and two-output digital mapping filter in both nonrecursive and recursive forms. The recursive realization being able to decrease drastically computing load utilizes the normal form that is robust to finite word length effects. As an application of the proposed mapping method, inverter-using power control system connected with a single-phase grid is shown. All analytical results are verified by numerical experiments and the usefulness of the newly proposed mapping method is confirmed.
