“…Repetitive control (RC), which is based on the internal model principle [5], can track any periodic signal and eliminate the steady-state tracking error. In [6] and [7], the digital form of the RC internal model is 1/(1 − Z −N ), and the fundamental time delay is Z −N , which means that the RC controller will not act in the first period when the instruction changes. Thus, the dynamic response of the RC controller is not satisfying and is suitable for fast-transient applications.…”

The repetitive control (RC) strategy is widely used in AC power systems because of its high performance in tracking period signal and suppressing steady-state error. However, the dynamic response of RC is determined by the fundamental period delay T 0 existing in the internal model. In the current study, a (nk ± i)-order harmonic RC structure is proposed to improve dynamic performance. The proposed structure has less data memory and can improve the tracking speed by n/2 times. T 0 proves the effectiveness of the (nk ± i)-order RC strategy. The simulation and experiments of (6k ± 1)-order and (4k ± 1)-order RC strategy used in the voltage source inverter is conducted in this study to control the harmonic current source, which shows the validity and advantages of the proposed structure.

“…A multiple feedback loop controller is typically composed of voltage control in the outer loop and current control in the inner loop. Numerous control strategies such as PI [9,10], predictive control [11,12], deadbeat control [13,14], and repetitive control [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] are used for controlling the outer and inner loops. However, these controllers have a problem to make a design of controller optimally, which should be considered on both outer loop and inner loop.…”

“…Studies on the repetitive control scheme can be classified into two categories: those focusing on compensating periodic components using the repetitive control scheme [15][16][17][18][19][20][21][22][23][24][25][26] and those focusing on improving the repetitive control scheme [27][28][29][30][31][32][33]. This study belongs to the first category.…”

“…A zero-phase odd-harmonic repetitive controller has been proposed to reduce data memory usage and ensure faster convergence of the tracking error [16,17]. Moreover, this controller can be employed in uninterruptible power supply (UPS) inverters to supply sinusoidal voltage under nonlinear loads [18][19][20][21][22][23]. Further, by connecting the repetitive controller in parallel, steady state and rapid response can be achieved and harmonic components can be reduced.…”

-This study proposes high-performance voltage controller design that employs a capacitor current control model for single-phase stand-alone inverters. The single-phase stand-alone inverter is analyzed via modeling, which is then used to design the controller. A design methodology is proposed to maximize the bandwidth of the feedback controller. Subsequently, to compensate for the problems caused by the bandwidth limitations of the controller, an error transfer function that includes the feedback controller is derived, and the stability of the repetitive control scheme is evaluated using the error transfer function. The digital repetitive controller is then implemented. The simulation and experimental results show that the performance of the proposed controller is high in a 1.5 kW singlephase stand-alone inverter prototype.

Abstract.A new voltage control method for single-phase full-bridge PWM inverters that having an output LC filter is proposed in this paper. The proposed voltage controller has a capability to realize a zero steadystate output voltage error with fast response. The zero steady-state output voltage error is achieved by using a controller that is derived by using the virtual LC resonant circuit. Fast response is obtained by using a virtual resistance that is connected in parallel with the filter capacitor. The validity of the proposed method is verified by experimental results.
