A PRE control scheme in single-phase inverter is adopted, namely connecting the proportional component with repetitive controller in parallel. This control scheme not only retains the characteristics of fast dynamic response from proportion link ,but also absorbs the advantages of no steady-state error in repetitive control .When the system is in stable operation condition, repetitive controller is used to resist periodic disturbance and thus improve the steady-state performance. Contrarily, the proportional component can feel mutation of input error and produce accommodation immediately to ensure the systems fast speed of response .The comprehensive theoretical analysis of this control strategy is given, and the system is designed in Matlab based on this theory, besides, the control scheme is achieved in the DSP platform by using digital control algorithm. Simulation and experimental results prove that the proposed scheme can achieve good dynamic and steady-state performance.

Repetitive Controller

There exist several challenges in the implementation of proportional multiple quasi-resonant (PMQR) control strategies in single-phase grid-connected H6 inverters, such as high computational costs and design complexity. To overcome these challenges, this paper proposes a proportional multiple quasi-resonant (PMQR)-type repetitive control (PMQR-type RC) scheme for single-phase grid-connected H6 inverters. In the control scheme, a repetitive controller and a proportional controller run in parallel. The repetitive controller is to improve the steady-state harmonics compensation ability, while the proportional controller can enhance the transient performance of the system. Both theoretical stability analysis and detailed design steps regarding the proposed control scheme are introduced. Finally, comparison results on a typical single-phase grid-connected H6 inverter with LC filter under a variety of control methods verify the capability of suppressing harmonics and the robust performance of the proposed control strategy against grid disturbances.

Repetitive Controller

This paper proposes a synchronous reference frame (SRF) control strategy for a single-phase, three-level, dual-buck photovoltaic (PV) inverter. The concept of virtual d-q transformation is adapted to the current control of the inverter, and the repetitive controller is implemented in the SRF. With the proposed control strategy, the memory allocation quantity for the repetitive controller is decreased and the capability of the current reference tracking is maximized. Thus, the proposed method significantly reduces the total harmonic distortion (THD) of the output current in both the continuous conduction mode (CCM) and the discontinuous conduction mode (DCM). In addition, the distortion of the output current is mostly composed of odd harmonics. Odd harmonic expressed to the even harmonic in SRF can be calculated using Park’s transformation. Therefore, a repetitive controller can improve dynamics by considering only even harmonic components in SRF rather than including all harmonics. The simulation and the experimental results verify the effectiveness of the proposed control strategy. The proposed method not only reduces the THD of the output current in both the CCM operation and the DCM operation, but also improves the dynamics of the current controller.
