“…The proportional, integral, and derivative (PID) controller has been utilized in the various control application in practice. Over 90% of the industrial processes utilize PID in their daily operation [16,17] due to its robustness, ease of maintenance, and simplicity [18,19]. The PID controller consists of proportional, integral, and derivative gains that scale the value of error between the input and output of the controller.…”

This paper represents a low complexity of the DVR controller by using a robust differentiator named as approximate classical sliding mode differentiator (ACSMD) to overcome the drawback of the linear differentiator. Additionally, utilize a nonlinear sliding variable named arctan function (sigmoid function) in order to keep the magnitude of the load voltage approximately 1pu, the THD at the standard level, improve the robustness property and maintain the steady-state error within a small bound. The most important issues of the power system network are power quality, the major problems of power quality are voltage sag/swell and harmonics which cause tripping or malfunctioning of the equipment. This paper gives an economic and effective solution by utilizing the dynamic voltage restorer to protect the sensitive loads from the disturbances that happened in the system such as voltage sag/swell and harmonics. The proposed system of the DVR is investigated by utilizing MATLAB/Simulink to enhance the disturbances when it occurs in a distribution system. The presents DVR model is evaluated by utilizing some of the popular voltage sag indices.

“…A PI control based voltage tracking of bridgeless power factor correction (BPFC) Cuk converter is proposed in [29], which has the advantages of faster steady state response and lower output voltage ripples. The output voltage of an Interleaved Cuk Converter (ICC) can be regulated using Genetic Algorithm (GA) tuned FOPID controller in the presence of input voltage variations [30]. The stabilization of output voltage of linearized model of a non-isolated DC-DC Cuk converter can be exercised in the presence of any disturbance, using GA tuned FOPID controller as suggested by the authors in [31].…”

Recently, the renewable energy applications require the development of highly efficient DC-DC converters with higher voltage transfer gain capability to meet out the increased global power demand. The non-isolated DC-DC converters are preferred due to certain drawbacks of isolated structures. The traditional boost, SEPIC (single-ended primary-inductor converter), and CUK based DC-DC converter structures are modified with additional power switches, diodes, and passive components in order to achieve high voltage gain. However, the modified structures with large number of active and passive elements suffer from the drawbacks of increased complexity of control algorithm, reduced power conversion efficiency and higher converter cost. Hence, the researchers started to explore more on single power switch configured non-isolated high step-up DC-DC converter topologies using hybrid concept. The research work presented in this paper explores such a high gain single-switch hybrid DC-DC converter structure that combines the conventional SEPIC and CUK topologies to achieve enhanced voltage gain. In the proposed hybrid topology, the input current is continuous during all modes of converter operation. Moreover, the power switch experiences only low voltage-current stress. The closed-loop configuration of the proposed hybrid converter is implemented using classic PID (Proportional+Integral+Derivative) and FOPID (Fractional Order PID) controllers, and simulated in MATLAB / SIMULINK environment with duty ratio D = 0.7 for the power switch. The results demonstrate that the dynamic performance of the converter with FOPID controller is much improved in terms of reduced settling time, overshoot, and ripples for the output voltage, as compared to that with classic PID controller.

“…The most practical situation is the second one where it is required to design a fractional‐order controller to improve the performance of an integer‐order system. An important example of this can be found in power electronic circuit applications and particularly switching DC/DC converters 3‐7,20,23‐47 . As can be noticed from most of these contributions, the designed fractional‐order controllers require digital signal processing techniques, which adds an extra overhead on present implementations of switching DC/DC converters in commercial products.…”

Switching DC/DC converters are closed loop systems requiring controllers to stabilize and optimize their performance. A practical method for designing these controllers through pole/zero placement adjustment is the K-factor method. This method can easily be implemented using RC op-amp circuits given a target crossover frequency and phase margin. Here, we extend this method to the fractional-order domain and present detailed analytical formulae to calculate all component values in two types of op-amp-based compensators. Mathematical analysis, circuit simulation, and experimental results all correlate very well.
