“… 11 Negi et al 21 used the PR controller to realize an improved damping strategy that has enough stability margin, but requires an accurate model of the system and high online computational requirements. Yanarates and Zhou 22 designed a novel PR controller to resolve the drawbacks of conventional PI controllers in terms of phase management. Xie et al 23 applied the PR controller to achieve a fixed switching frequency and mitigate steady-state error; however, it is not practical to implement by either analog or digital signal processors.…”

The grid-connected inverter is the key to ensure stable, reliable, safe, and efficient operation of the power generation system; the quality of the grid-connected output current waveform directly affects the performance of the entire power generation system. To improve the anti-interference performance and reduce the output current harmonic content of the grid-connected inverter, an improved control strategy that combined repetitive control (RC) and auto disturbance rejection control (ADRC) is designed in this paper. Firstly, decoupled the ADRC to realize the individual adaptation between tracking performance parameters and anti-interference performance parameters of the controller, through which the difficulty of adjusting parameters is reduced. Secondly, the control approach is devised by adding RC to ADRC. To demonstrate the effectiveness of the proposed method in this paper, detailed experimental studies are conducted using proportional integral control, traditional ADRC, and the proposed method under normal power grids, weak power grids, and periodic disturbances. And dynamic performance simulation experiment is done to verify the dynamic performance of the self-disturbance rejection controller before and after the addition of RC links. The results indicated the effectiveness and feasibility of the proposed method. Finally, after simulation, the steady state and dynamic performance are conducted on a hardware testing platform. The impacts of the obtained results indicate the effectiveness and feasibility of the control algorithm proposed, the ability to suppress intermediate frequency disturbances is improved, the bandwidth of the auto disturbance rejection controller is expanded, and the harmonic content of the output current is depressed.

“…Nevertheless, a main drawback of SMC is chattering which is the cost of the high robustness that is generated by discontinuous control law. 25 Several solutions had appeared during the recent decades and probably the most efficient one is the super-twisting algorithm (STA). 26 This tool is a dynamic extension that generates a continuous control integrated signal that shadows the discontinuity of the SMC.…”

This research presents and compares the outcomes of experimental implementations of different fuzzy logic control structures for a proton exchange membrane fuel cell (PEMFC). These devices are well known for their capability to transform chemical energy into electrical with low emissions. Commonly, a PEMFC has a linkage with a boost converter which allows a suitable end‐user voltage through a nonlinear control law. Hence, the contribution in this sense is the experimental comparison of two fuzzy logic strategies known as type‐1 and type‐2 that were implemented in a PEMFC system. The approaches were embedded in a control board dSPACE 1102 which also has the capability to acquire data. The contrast of results showed capabilities improvement against disturbances in terms of error reduction, control signal, and robustness.

“…PV systems basically consist of a PV array and switch mode power supply (SMPS). SMPSs are the most essential components in PV systems owing to their functions of increasing the efficiency, providing reliability, and cost-effectiveness (Yanarates and Zhou, 2022). The primary function of power electronic converters in PV systems is to capture the maximum power generation from the PV array and feed the power into the grid (Li et al, 2011;Beriber and Talha, 2013).…”

In this study, a novel PV emulator and the state-of-art learning–based real-time hybrid global search adaptive perturb and observe (P&O) maximum power point tracking (MPPT) algorithm have been presented. The prime objective of the constructed emulator based on integration of unilluminated solar panels with an external current source to overcome the constraints such as the need for wide surrounding space, high installation cost, and lack of control over the environmental conditions. Moreover, the developed algorithm resolved the drawbacks of the conventional P&O MPPT method associated with the use of a constant perturbation size that leads to poor transient response, high continuous steady-state oscillation, and inefficient tracking performance of maximum power point voltage in the presence of partial shading. The intended algorithm has been verified using MATLAB/Simulink by applying comparative analysis with the conventional P&O MPPT. In addition, the performance of the proposed control scheme is validated experimentally with the implementation of MATLAB/Simulink/Stateflow a on dSPACE Real-Time-Interface (RTI) 1007 processor board and DS2004 A/D and CP4002 Digital I/O boards. The results indicate that the algorithm is effective in reducing power losses and faster in tracking the speed of the maximum power point with less oscillation. In addition, excellent dynamic characteristics of the proposed emulator have been proven to be an ideal tool for testing PV inverters and various maximum power point tracking (MPPT) algorithms for commercial applications and university studies.
