“…In this paper, u ck (n) is collectively referred to as the kth cosine wave. M k is the kth cosine wave amplitude; δ k is the initial phase of the kth cosine wave; T is the sampling time interval; ω is the fundamental angular frequency; Θ is the value set of k. Considering the main low-order harmonics of the actual three-phase grid-connected inverter are 5 and 7 times in practice (Bourguiba et al, 2016), and it is also necessary to control the fundamental wave, the Θ of QSE is set as {1,5,7}.…”

“…The current closed-loop controller is an important factor affecting output current harmonics' performance (Cárdenas et al, 2012;Tuan and Santoso, 2016). There are many effective current closed-loop control algorithms for suppressing current harmonics, and the main difference between them is the harmonic extraction method (Castilla et al, 2013;Kulkarni and John, 2013;Zhao et al, 2013;Bourguiba et al, 2016;Wang et al, 2016;Qian et al, 2017;Zhaoyang et al, 2017;Busarello et al, 2018;Hu et al, 2018;McDonald and Li, 2018;Chen et al, 2019;Choi and Sarlioglu, 2019;Fei et al, 2019;Song et al, 2020).…”

“…Proportional multi-resonance control uses multiple quasiresonance controllers (MQR) to suppress some major low-order harmonics (Castilla et al, 2013;Bourguiba et al, 2016;Wang et al, 2016;Qian et al, 2017;Zhaoyang et al, 2017;Hu et al, 2018;Choi and Sarlioglu, 2019;Song et al, 2020). It takes advantage of the fact that the amplitudes of some lower harmonics, especially odd harmonics, are usually larger than that of the higher harmonics (Qian et al, 2017).…”

Grid-connected inverters need to reduce current harmonics as much as possible. After introducing the input signal’s fundamental and main harmonic quadrature components, a discrete state model is created, and the discrete observer design method is used to propose a harmonic extraction algorithm called quadrature sinewave extractor (QSE). The QSE is a stable recursive operator with the advantages of no phase displacement and the ability to eliminate mutual influence between harmonic components. Compared to the widely used proportional multi-resonant controller, QSE can reduce current harmonics and improve system stable performance by using it in the current control of grid-connected inverters. Finally, comparative experiments on a three-phase grid-connected inverter are used to verify the proposed method’s effectiveness.

“…In [7], a proportional-integral (PI) controller is used, but the general problems of this controller include its poor performance, the existence of a steady-state error in load changing, the presence of disturbances, and the failure to follow the sinusoidal reference. The proportional-resonance (PR) controller is provided in [8], [9] for single-phase and three-phase inverters. Although this controller performs better than PI, it has problems such as the need for fine-tuning and high frequency sensitivity.…”

This paper proposes a sliding mode controller based on robust model reference adaptive proportional-integral (RMRA-PI) control for a stand-alone voltage source inverter (SA-VSI). The proposed controller has two control loops where the coefficients of PI controller are regulated by the adaptive sliding law. This method is used to regulate the output voltage of the inverter under different load conditions and uncertainty, and adapts the output to the reference model to reduce the total harmonic distortion (THD). In this paper, the stability of the proposed controller is proven by using Lyapunov' s theory and Barbalet's lemma. The proposed controller performs well in voltage regulation such as low THD under sudden load change and uncertainty. Also, the results of the proposed controller are compared with PI controller to show the effectiveness of the presented control system. Index Terms--Robust model reference adaptive proportionalintegral (RMRA-PI) control, stand-alone inverter, three-phase inverter, voltage control, Lyapunov' 's theory.

<p><span lang="EN-US">Harmonics and grid synchronization are one of the major problems faced when dealing with a single-phase system. The development of technology in the PV system makes the consumer to use it in a wide range. The power transferred from PV to grid needs DC to AC conversion process which is done by static devices operating with the higher frequencies that causes the harmonics in the grid connected system. The main aim of the paper is to implement grid synchronization and reduce total harmonic distortion in a single-phase grid connected system. The design of LCL filter is addressed in this paper which depends on current ripple, filter size and switching ripple attenuation. In order to account the harmonic content, the FFT analysis is made both in analysis and Matlab Simulink. The Proportional Resonant (PR) controller is developed and work along with LCL filter for reducing the harmonic content. The stability of the system with PR is analyzed using root locus and bode plots and results are compared with PI controls. The result shows that PR controller performs better compared to the PI controller for reducing the harmonic content present in the single-phase system and for improving the system stability.</span></p>
