LMI-Based Robust H∞ Control of Photovoltaic Systems with Takagi-Sugeno Fuzzy Models [PDF]

EPJ Web of Conferences
This article develops a Takagi-Sugeno (T-S) fuzzy controller for solar systems' Maximum Power Point Tracking (MPPT). The nonlinear dynamics of the PV generator and the Boost converter are described using a continuous-time T-S fuzzy model.

A novel hybrid analytical/iterative method to extract the single-diode model's parameters using Lambert's W-function

Energy Conversion and Management: X, 2023
The evaluation of photovoltaic device performance is based on the I-V characteristic curve. Unfortunately, the data sheets provided by the manufacturers only include data at standard test conditions, which requires the construction of a model capable of ...

On physical web models

2016 International Siberian Conference on Control and Communications (SIBCON), 2016
The Physical Web is a generic term describes interconnection of physical objects and web. The Physical Web lets present physical objects in a web. There are different ways to do that and we will discuss them in our paper. Usually, the web presentation for a physical object could be implemented with the help of mobile devices.
