Natural gas peak demand forecasting is crucial for efficient network infrastructure spending and stock planning. Herein, long-term forecasting is studied, using data of the Tunisian Company of Electricity and Gas (STEG) as case study. Gas peak flow data preprocessing is elaborated as preliminary step. Ridge regressor, support vector regressor (SVR) and K-nearest neighbors (K-NN) are implemented to make long-term forecasting with different resolutions (daily, monthly). Based on the best performing base models, two types of ensemble models are implemented: simple average and weighted average. The study provides important results to decision-makers in order to optimize the energy policies.

Mechanomyography (MMG), in particular the acoustic myogram (AMG), is a non-invasive technique used for recording the sound signal produced by muscles. It can be used to explore the neurophysiological and morphological characteristics of muscles and thus highlight fatigue or even the modification of these characteristics of the latter. In this article, we de velop a measurement platform to record the AMG muscle activity produced during six hand movements. The idea of this work is to show the capabilities of our platform to produce and help to recognize multiple hand movements. The sensor used consists of three condenser microphones with high sensitivity electrets placed on the forearm in order to be more sensitive to extrinsic and intrinsic muscles. The experimental results re ve al visible muscle activity with different levels of amplitude and also frequency, clearly correlated with the strength and vibrations of the muscle fibers.

this paper shows a methodology for optimal sizing of island micro grids in Djerba, Tunisia containing photovoltaic panels, a wind turbine, and a tidal turbine. The battery storage system and a diesel generator are used as compensating energy sources. The process aims to find a configuration within a set of system components that meets the required system reliability requirements. The modeling of PV/wind/tidal micro grids is considered as the first step in the optimization of the selection process. This paper aims to study the sizing and optimization of the hybrid power system to supply the load of the studied location in Djerba Island, Tunisia. The objective functions are selected by minimizing the life cycle cost (LCC) and the embodied energy (EE) for a variable probability of loss of power supply (LPSP 0%). MATLAB software is used in all simulations and programming of the micro grid system. Real weather data and a load profile are used to design and evaluate the sizing and optimization results, during the year 2020 to determine the highest component size of a micro grid system.

Quantum-dot cellular automata (QCA) offers significant area reduction due to nano-size, high operational speed with significantly low power levels. It is a wireless technology and does not use current or voltage to carry information. Instead, it utilizes the positioning of the electrons. In this paper, an optimal 1:2 demultiplexer based on QCA technology has been investigated. QCAPro software has been used to estimated the energy dissipation of the suggested design. Simulation is achieved for the suggested design using QCADesigner software. The proposed design has less number of cells, area and energy dissipation as compared to the previous structures.

The maximum power point tracking algorithm in wind power system design is considered an important point, to increase the efficiency of wind turbines power, in addition to regulating the voltage and frequency loops, energy must be extracted from the wind very efficiently, so it is necessary to design an effective control strategy. This paper presents an adaptive tuning structure, for capturing the maximum power points of controlling the wind energy conversion system, according to a permanent magnet synchronous generator. The optimum rotational speed of the generator is obtained utilizing the tip speed ratio strategy. Maximum power extracted at each wind speed is maintained, using a dimensional fuzzy logic control (DFLC) that is applied to the machine side converter. Adaptive DFLC controller is used in complex non-linear systems. The new control adopts two ideas, first to locate system states to a specific region in the form of calculating dimensional (distances, surface), then to design a fuzzy control law that will maintain the system in this zone. To confirm the efficiency and reliability of the suggested adaptive control, a simulation was executed using the MATLAB/Simulink program. The results showed the superiority of the new control as it was observed that the control can extract maximum power under variations of the wind speed profile, through its response speed and settling time. The paper contains extensive results.
最大功率点跟踪算法在风电系统设计中被认为是一个重要的点,要提高风力发电机组的发电效率,除了对电压回路和频率回路进行调节外,还必须非常高效地从风中提取能量,因此有必要设计一种有效的控制策略。本文以永磁同步发电机为例,提出了一种自适应调谐结构,用于捕获控制风能转换系统的最大功率点。利用叶尖速比策略得到了发电机的最佳转速。在每个风速提取的最大功率保持,使用一个维度模糊逻辑控制(DFLC),应用于机器侧转换器。自适应DFLC控制器用于复杂非线性系统。该控制方法采用两种思路,首先通过计算维度(距离、曲面)的形式将系统状态定位到特定区域,然后设计模糊控制律使系统保持在该区域内。为了验证所提自适应控制的有效性和可靠性,利用MATLAB/Simulink程序进行了仿真。结果表明,在风速廓线变化的情况下,该控制方法的响应速度和稳定时间都能提取出最大功率。这篇论文包含了广泛的结果。

Almost all industrial wind turbine failures are caused by bearing degeneration. As a critical part of this functionality, precisely estimating the remaining usable life (RUL) of the bearings is necessary in order to ensure the reliability and availability of energy generation. This work investigates how to build a classification model in Python to estimate the RUL of a wind turbine main bearing. Making use of SCADA data Given by the Harvard Dataverse data set, we select only the four most physical characteristics from this data set to solve this challenge. Temperature, viscosity, dynamic load, and fatigue damage are all factors to consider. The suggested methods is based on a concept that was previously developed in the literature for prediction in other discipline. This paper also assesses which model is best for forecasting failure on the given data set. This assessment is carried out in order to determine that linear regression is the best method for producing a model capable of reducing variation and improving the metrics of our model with an accuracy level of 99 percent for daily prediction. This enables the development of a new sort of intelligent intention.
几乎所有工业风力发电机的故障都是由轴承退化引起的。作为该功能的关键部分,为了确保发电的可靠性和可用性,精确估计轴承的剩余使用寿命(RUL)是必要的。本文研究了如何在Python中建立一个分类模型来估计风力发电机主轴承的RUL。利用哈佛数据厌恶数据集给出的SCADA数据,我们从该数据集中只选择四个最物理的特征来解决这个挑战。温度、粘度、动载荷和疲劳损伤都是需要考虑的因素。建议的方法是基于先前在其他学科的预测文献中发展起来的概念。本文还评估了在给定数据集上哪种模型最适合预测故障。进行此评估是为了确定线性回归是产生能够减少变化并以99%的准确度水平提高模型度量的模型的最佳方法,用于日常预测。这使得一种新的智能意图得以发展。

Wind turbines are increasing their generation energy capacity, which requires an increase in reliability. One of the most relevant failures that occur in wind turbines is the one in the main bearing. The study of methods that allows predicting the behavior of Wind Turbines under different operation conditions will permit a forecast of any possible failure in the elements of the device. The current work presents the first results in developing a wind turbine digital twin using SCADA data. This DT should allow to estimate and simulate the behavior of the WT and be an additional tool in the prediction of failures. The used platform is MATLAB and its Simulink and Simscape modules.

This paper investigates the problem of designing controllers to enlarge the stability domain of polynomial discrete systems. In order to deal with this problem, we propose a method for computing a linear feedback control law, which extends the largest estimate of the stability domain. The designing of the control law is established in the form of an optimization problem that focuses on expanding the stability domain. An application example is presented to illustrate the efficiency of the proposed controller law for maximizing stability domain. The simulation results prove clearly the capability of our linear controller approach to increase the radium of the stability domain for the studied nonlinear system.

The simulation results prove clearly the capability of our linear controller approach to increase the radium of the stability domain for the studied nonlinear system.","PeriodicalId":6874,"journal":{"name":"2022 5th International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"11 1","pages":"489-493"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85193005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the frequent tasks of a robotic system is to go from an initial position to another location or to change its actual configuration to some desired one. Thus, an efficient as well as simple control law should be applied to achieve such objective. Despite the presence of several control approaches of robotic systems, this work proposes mainly a design method of an affine state-feedback controller for the problem of position control and by considering the general form of the nonlinear dynamics. The adopted methodology is chiefly based on the development of a linear dynamic model defined around the desired position. Moreover, the linear matrix inequality technique is used to compute the feedback gains of the control law. An illustrative example and a comparison with the CTC controller are given at the end to show the validity and efficiency of the proposed design and control approach.
机器人系统的一个常见任务是从一个初始位置移动到另一个位置或将其实际结构改变为某些期望的结构。因此,要实现这一目标,必须采用一种既有效又简单的控制律。尽管存在几种机器人系统的控制方法,本工作主要提出了一种仿射状态反馈控制器的设计方法,用于位置控制问题,并考虑了非线性动力学的一般形式。所采用的方法主要是基于围绕期望位置定义的线性动态模型的发展。利用线性矩阵不等式技术计算控制律的反馈增益。最后给出了一个示例,并与CTC控制器进行了比较,以证明所提出的设计和控制方法的有效性和有效性。
