“…In an economy burdened by the costs of increasingly scarce oil and natural gas, and a planet suffering the impact of fossil fuel and climate change, the technological revolution of this era is renewable energy [1][2][3][4][5]. Sunlight, wind, water, geothermal heat and plant biomass are all essentially limitless resources and they are all proven technologies that work at any time used.…”

The present work concerns an experimental study of the utilization of insulation and phase change material PCM in building structures. It particularly presents an efficient heating system modulated with thermal insulations and phase change materials where an appropriate experimental setup is devised to help in making energy management possible. The experimental setup consists of insulated and non-insulated room models that enable direct observation of different heat transfer results between a well-insulated room with PCM (paraffin wax) and a non-insulated room. The integrated heating-insulation-PCM set-up proved that it can work toward a more comfortable and efficient system where energy bills are 74% lower with an average improvement factor reaching 50% in comparison with the non-insulated room model.

“…The versatility of buck–boost converter to transform its supply voltage into a higher/lower output makes it an alternative for applications requiring DC voltage regulation, ranging from light-emitting diode (LED) lighting [ 1 ] to renewable energy sources [ 2 , 3 ], microgrids [ 4 ], and battery charging [ 5 , 6 ], to mention the most relevant. Biomedicine applications [ 7 , 8 , 9 ] take special relevance due to their impact in human’s health, since the need for appropriate energy management/harvesting/storage strategies to be applied in micro/nano-scale is one of the main drawbacks of emerging cardiac technologies, for instance.…”

Fractional-Order Approximation of PID Controller for Buck–Boost Converters

Viability of a fractional-order proportional–integral–derivative (PID) approximation to regulate voltage in buck–boost converters is investigated. The converter applications range not only to high-power ones but also in micro/nano-scale systems from biomedicine for energy management/harvesting. Using a classic closed-loop control diagram the controller effectiveness is determined. Fractional calculus is considered due to its ability at modeling different types of systems accurately. The non-integer approach is integrated into the control strategy through a Laplacian operator biquadratic approximation to generate a flat phase curve in the system closed-loop frequency response. The controller synthesis considers both robustness and closed-loop performance to ensure a fast and stable regulation characteristic. A simple tuning method provides the appropriate gains to meet design requirements. The superiority of proposed approach, determined by comparing the obtained time constants with those from typical PID controllers, confirms it as alternative to controller non-minimum phases systems. Experimental realization of the resulting controller, implemented through resistor–capacitor (RC) circuits and operational amplifiers (OPAMPs) in adder configuration, confirms its effectiveness and viability.
