“…Needs on clean energy will have the fastest growth in the electricity sector. Recently, photovoltaic energy is particularly used in space, transportation applications and in building-integrated photovoltaic; in which solar arrays are in the roofs of the buildings and houses [1]- [4]. Accurately, the generation of photovoltaic (PV) power is dependent on temperature degree and chiefly irradiation level.…”

<span lang="EN-US">Microprocessors and microcontrollers are mostly used to control electrical systems. These chips front into problems while monitoring systems that need heavy computing and important processing. Likewise, they fail while handling inputs and outputs speeds, especially with multi-channel photovoltaic (PV) systems. In comparison to a digital signal processor (DSP) and microcontroller implementations, field programmable gate array (FPGA) device is able to integrate a great number of PV channels and to achieve short development time, cost less and more flexible operation. As well, new control algorithms are increasingly complex; using new performing technologies is very motivating. Mainly, FPGA technology is adopted thanks to its ability to control complex applications and intelligent laws. In opposition to traditional controls, fuzzy logic based control presents more efficiency and reliability response for non-linear systems. Therefore, this paper deals with the execution of the fuzzy-based maximum power point tracking (MPPT) technique by the means of the FPGA chip for a multi-channel photovoltaic system. A multi-channel photovoltaic system is designed. Then, the FPGA circuit is investigated to get benefits from this hardware solution. Since software implementation way integrates a limited number of PV panels, hardware implementation is a promising solution that reduces execution time and therefore controls a huge number of photovoltaic channels. Finally, results of simulation of the fuzzy technique implementation on FPGA chip show that the proposed PV system controls more than 4400 channels. Therefore, the system output power is increased and the system profitability is improved.</span>

In this study, a model reference adaptive state-dependent Riccati equation (MRASDRE) is proposed as a maximum power point tracking (MPPT) controller to extract the maximum power from a photovoltaic (PV) array mounted on an orbiting satellite. In the structure of the proposed MPPT, a fuzzy logic controller (FLC) is used to estimate the reference voltage of the PV array at the maximum power point (MPP), and an adaptive mechanism is used to compensate for the difference between the PV system and the reference model. The model reference generates the duty cycle for damping the oscillations of the DC-DC converter and tracking the MPP. A Lyapunov stability theory is used to obtain an adaption law to tune the gains of the adaptive mechanism. Hence, the stability of the closed system can be guaranteed, and the maximum power point (MPP) can be captured. To evaluate the performance of the proposed MPPT used in an orbiting satellite, the outer space environment is simulated. Also, an electrical power supply (EPS) is proposed to manage the generation and consumption of satellites. The efficiency of the proposed MPPT is verified in the simulation tests.
