“…The most significant of these is that when developing a fuzzy controller, the trial and error method is typically required. In order to develop a fuzzy controller, no systematic procedure has been established in [21][22][23][24]. Typically, FLC performance is not known until the design phase is complete.…”

“…The basic structure of the boost converter is depicted in Fig 1 . The output voltage of a step-up converter is increased relative to the input voltage in the same way that the voltage of a step-up transformer is increased relative to the input voltage. There is no difference between the input and output powers because of the rule of conservation of energy [23].…”

“…The basic structure of FIS is given in Fig 9 . The process of decomposing a system's input into one or more fuzzy sets is called fuzzification. There are numerous curve types that can be used for MF, but trapezoidal or triangular-shaped MF are the most frequently used due to their ease of representation in embedded controllers [21][22][23]. The knowledge base is a collection of rules, while the data base is formed through the conversion of crisp to fuzzy input.…”

Demand of Power electronics converter is increased due to the rapid increase of green re-sources. The distributed nature of uncontrolled renewable energy resources are connected with the grid via power electronics converter. DC-DC converters are high-frequency current conversion circuits that use transformers, inductors, and capacitors to smooth switching noise into regulated DC voltages. In this study, a comparative performance analysis of Proportional integral Derivative (PID) and fuzzy logic controller (FLC) for DC-DC Boost Converter is presented. PID-based controller for dynamic boosting of DC-DC boost converter was replaced by Fuzzy Inference system (FIS) to study the system behavior. Five different membership functions were performed to observe the response of the system for DC -DC boost converter with FIS controller. The performances of FIS-based controller and PID-based controller for DC-DC boost converter were compared in detail. Also, the proposed techniques for the switching mode of DC-DC converter have been applied. The performance analysis of both PID and fuzzy controller was simulated using MAT LAB. The results of FIS based approach are better than PID based controller in terms of transient responses.

“…Te proportional integral diferential control (PID) is most widely used in buck-boost converter to realize single closed-loop or double closed-loop control. It has the advantages of simple principle, easy implementation, and independence of system model [4,5]. However, the buckboost converter is a nonlinear time-varying system, and a PID cannot achieve the desired control efect, especially when the power source or load changes suddenly in a large range, and it even makes the converter unstable [6,7].…”

Normally, the buck-boost converter adopts single or double closed-loop control, and there are differences in control and parameters for different working modes and loads. In this study, a unified control method, the passivity-based control (PBC), is applied to a buck-boost converter for different loads, including constant resistance load (CRL), constant power load (CPL), and battery load. The PBC is a nonlinear control based on energy dissipation principle, and it has strong robustness to parameter interference and external disturbance, and it also has the advantages of simple design and simple implementation. Although many research studies have been conducted before, the voltage and current-related power losses are considered, and different load models are also compared in this research. The detailed mathematical model, control principle, and controller design of the buck-boost converter are thoroughly analysed. In addition, SIMULINK-based simulation results and experimental verification results of different loads are also given in the paper. Also, the PBC has smaller current overshot and smaller current ripples compared with PI control in different loads condition.

“…Since the output power from photovoltaic energy changes due to changing amount of sunlight, in order to maintain the DC-link voltage at a set value, the controller parameters for the bidirectional buck-boost converter must be designed properly so that the converter will have good output performance. The architecture of the commonly adopted traditional P-I controller is simple and does not require complex calculations, but the controller parameters can only be adjusted through the trial-and-error method, thus requiring more time to obtain the controller parameters [6][7][8]. Furthermore, whereas the controller designed using the Bode plot can obtain the controller parameters quickly but does not take the converter's dynamic characteristic of wide operating spectrum into consideration, and thus is only able to obtain the dynamic response under certain conditions; once the operating point changes, the system will be unable to operate under the better performance response [9,10].…”

The purpose of this paper is to develop a photovoltaic module array with an energy storage system that has equalizing charge/discharge controls for regulating the power supply to the grid. Firstly, the boost converter is used in conjunction with maximum power point tracking (MPPT) such that the photovoltaic module array (PVMA) can output maximum power at any time. The battery equalizing charge/discharge architecture is composed of multiple sets of bidirectional buck–boost soft-switching converters in serial connection in order to achieve zero-voltage switching (ZVS) and zero-current switching (ZCS) so that when the charge/discharge power is above 150 W, the converter efficiency can be increased by 3%. The voltage and current signals from the battery are captured and input into the digital signal processor (DSP) to establish an equalizing charge/discharge control rule. For the output voltage control of the bidirectional buck–boost soft-switching converter, the dynamic mode is derived by first using the step response at chosen operating point, then quantitatively designing the controller parameters for the converter, so that the output voltage response can meet the pre-defined performance specifications. Finally, actual test results prove that the equalizing charge/discharge time of the quantitative design controller is shortened by more than 10% when compared to the traditional proportional-integral (P-I) controller regardless of charging or discharging; this also proves that the design of the photovoltaic module array with an energy storage system (ESS) that has equalizing charge/discharge controls is valid.
