Parameters Degradation Analysis of a Silicon Solar Cell in Dark/Light Condition using Measured I-V Data

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 1, Page # 1151–1156, 2021; DOI: 10.25046/aj0601129
Abstract:

In this paper, we investigate and analyze parameters degradation in a typical photovoltaic (PV) cell, which lead to power loss under dark as well as light condition using measured current-voltage (I-V) data. A nonlinear least squares method to extract the parameters such as the reverse saturation currents, the ideality factors, the series and shunt resistances…

Modeling and Implementation of Quadcopter Autonomous Flight Based on Alternative Methods to Determine Propeller Parameters

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 5, Page # 727–741, 2020; DOI: 10.25046/aj050589
Abstract:

To properly simulate and implement a quadcopter flight control for intended load and flight conditions, the quadcopter model must have parameters on various relationships including propeller thrust-torque, thrust-PWM, and thrust–angular speed to a certain level of accuracy. Thrust-torque modeling requires an expensive reaction torque measurement sensor. In the absence of sophisticated equipment, the study comes…
