Physics of potential-induced degradation in bifacial p-PERC solar cells

, 2019
The combination of increasing operational voltages beyond 1000 V in photovoltaic (PV) installations and the emergence of new PV technologies requires a critical assessment of the susceptibility to potential-induced degradation (PID).

Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

RDA Recommendation on PID Kernel Information (draft)

, 2018
Global middleware infrastructure is insufficient for robust data identification, discovery, and use. While infrastructure is emerging within sub-ecosystems such as the DOI ecosystem of services purposed for data and literature objects (i.e., DataCite ...

Designing ZV and ZVD Input Shapers Using the Designed Fixed Output Response Method to Suppress Residual Vibration of Overhead Crane Systems With Trolley Traveling and Payload Hoisting

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Classical Zero Vibration (ZV) and Zero Vibration and Derivative (ZVD) input shapers are designed around a fixed nominal natural frequency and cannot accommodate the time‐varying dynamics introduced when an overhead crane simultaneously travels and hoists a payload.

TD3-Based Reinforcement Learning for Adaptive PID-like Control of Uncertain Dynamical Systems

Mathematics
This paper presents a TD3-based reinforcement learning framework for adaptive PID-like control of uncertain dynamical systems. Although proportional–integral–derivative (PID) control remains widely used because of its simplicity, interpretability, and ...

Irreversible damage at high levels of potential-induced degradation on photovoltaic modules: A test campaign

, 2017
Potential-induced degradation (PID) of photovoltaic (PV) modules gets a lot of attention since 2010 when Solon published their findings about a degradation mechanism in their PV modules caused by high potential differences between the solar cell and the ...

Degradation of Crystalline Si‐Based Solar Modules With Varying Material Combinations—Part I: Encapsulant Degradation

Progress in Photovoltaics: Research and Applications, EarlyView.
This work deals with the degradation of solar modules with varying material combinations under accelerated aging conditions. By in situ moisture measurements and simulations of oxygen ingress, the consumption of stabilizing additives and polymer degradation can be correlated spatially resolved with the penetrating stressors.
