“…The performance of this algorithm is not suitable in steady state because it forces the output power to oscillate around MPP. In addition, algorithm performance is poor in MPP rapid changes, because it cannot distinguish between changes in environment variation condition and inherent perturbation algorithm (Elbaset et al, 2016; John et al, 2017).…”

This paper proposes a robust second order sliding mode controller as maximum power point tracking (MPPT) technique in a photovoltaic (PV) boost dc-dc converter with applications to stand-alone systems. The proposed method is independent respect to load type, robust against parametric uncertainties and disturbances. By Lyapunov theorem the asymptotic stability of the closed loop control system is proven. The proposed second order sliding mode controller is simulated with Matlab software and experimental set up in presence of sinusoidal disturbances on output voltage.

This paper presents design of a Maximum Power Point Tracking (MPPT) circuit and its functionality for tuning the maximum power transfer from an energy harvester (EH) unit. Simple and practical "Perturb and Observe" (P&O) algorithm is investigated and implemented. We describe the circuit functionality and the improvements that have been introduced to the original algorithm. The proposed MPPT design is divided into three main blocks. The output signal is being generated by the PWM or PFM block. The tracking speed has been enhanced by implementing a variable step size in the "Tracking Block". Finally, the overall power consumption of the MPPT circuit itself is controlled by the "Power Management Block", which manages delivering the clock signal to the rest of the circuit. The RTL code of the proposed MPPT has been created in Verilog, synthesized and placed-and-routed in a general purpose 130 nm CMOS technology.

“…Perturb and Observe (P&O) [4] technique is a standout amongst the most widely recognized customary strategy utilized because of its simplicity of execution yet does not indicate extraordinary preferred standpoint in regard of number of emphases, non-direct conditions and power misfortune [5]. Here the working point over the PV control bend is iteratively moved to look for the pinnacle control and the power yields will dependably have an oscillatory nature because of the nonstop bother.…”

<p>The inborn non-direct power voltage trademark bends concerning barometrical temperature and light makes the photovoltaic (PV) source a discontinuous one. Maximum power point (MPPT) following is a procedure through which most extreme accessible power is yielded from the PV for the given purpose of time. Prior, the customary MPPT methods, for example, perturb and observe, incremental conductance, hill climbing and so forth strategies were utilized and these methods stayed inadequate when the PV source is partially shaded (PS), since amid (PS) the power voltage (P-V) bends show different power crests. There wins each possibility that the ordinary calculations will stall out to the local maximum point and the global maximum point won't be accomplished and in this way control misfortune is brought about. The metaheuristic calculations give better arrangements however confront the downside of high weight on processor and enormous number of information prerequisites. In this way, in this paper, a novel calculation in light of invasive weed optimisation (IWO) technique is utilized to locate the Global maximum point for MPPT under in part shaded condition and it is contrasted and its nearby partner differential evolution(DE) MPPT algorithm and furthermore with the very much settled in perturb and observe (P&O) calculation. The proposed calculation is actualized in MATLAB condition and tried on a 3-board PV cluster arrangement of 150 W. The flexibility of the calculation is tried through various experiments and the outcomes demonstrate the effectiveness and exactness of the proposed calculation in finding the global maximum point.</p>
