En este trabajo se emplea el solver rhoCentralFoam incluido en la librería de acceso libre OpenFOAM para el modelado y simulación de la propagación de ondas de choque y su interacción con paredes sólidas cóncavas. Se desea estudiar el fenómeno inestacionario correspondiente a la reflexión de ondas de choque en paredes reflectantes curvas. Este tipo de reflexiónes, por su carácter inestacionario, posee tres variables independientes (x, y, t) y son fenómenos más complejos que aquellos generados en flujos estacionarios o pseudo-estacionarios que dependen de dos variables independientes. Los resultados numéricos obtenidos capturan adecuadamente las estructuras de ondas que se producen durante la reflexión, así como sus transiciones.
在此基础上,提出了一种方法,利用开放存取库OpenFOAM中的rhoCentralFoam求解器来建模和仿真冲击波的传播及其与凹实壁的相互作用。我们希望研究与激波在弯曲反射壁上反射有关的不稳定现象。这种类型的反射,由于其非稳态特性,有三个自变量(x, y, t),比那些在稳态或伪稳态流中产生的现象更复杂,后者依赖于两个自变量。在本研究中,我们分析了在反射过程中发生的波结构及其跃迁。

In the development of microwave systems it is important to be able to characterize devices and components in isolation with the least error possible. In this context, TRL (Through-Reflect-Line) calibration techniques are a versatile tool which allows to extract the S parameters of a two-port network minimizing the parasitic effects of measurement circuitry and device mounting. This work presents the design, simulation and measurement of a TRL calibration kit implemented using microstrip lines in a low-cost FR4 substrate. The designed kit is used to extract the S parameters of a capacitor, comparing the simulations with the obtained measurements.
在微波系统的开发中,能够以最小的误差隔离地表征器件和组件是很重要的。在这种情况下,TRL(透反射线)校准技术是一种通用工具,它允许提取双端口网络的S参数,最大限度地减少测量电路和设备安装的寄生效应。本工作介绍了在低成本FR4基板上使用微带线实现的TRL校准套件的设计,仿真和测量。利用所设计的工具提取电容器的S参数,并将模拟结果与实测结果进行比较。

Modular Multilevel Converters are being widely used in high-power applications such as High-Voltage Direct Current transmission due to the main advantages of scalability, modular configuration and high-quality power. For industrial applications, hundreds of power cells have to be connected in a cascade to reach high-power ratios. However, most of the current academic research is validated using prototypes equipped with a low number of power cells. Consequently, this paper presents the testing and start-up procedure of 60 power cells Modular Multilevel Converter test-bench based on an OPAL-RT real-time controller and power stage. Partial experimental results are presented.
模块化多电平变换器由于其可扩展性、模块化结构和高质量的功率等优点,在高压直流传输等大功率应用中得到了广泛的应用。在工业应用中,为了达到高功率比,必须将数百个动力电池级联起来。然而,目前的大多数学术研究都是通过配备少量动力电池的原型来验证的。因此,本文给出了基于OPAL-RT实时控制器和功率级的60节功率电池模块化多电平变换器试验台的测试和启动过程。给出了部分实验结果。

Making a double pendulum walk: from compass- to whip-like gait 双摆行走:从指南针到鞭子般的步态
Pub Date : 2022-09-07 DOI: 10.1109/ARGENCON55245.2022.9939939

The double pendulum is the main mechanical structure on which simple biped robots with compass-like gait are based. Although being very energy efficient, the compass-like gait bears the inherent problems of forcing the swing-leg tip to below-ground position while walking and allowing for almost no terrain irregularities. In this paper, an underactuated biped based on the double pendulum is made to walk via swinging the leg in the direction opposite to that of the compass-like gait. Actuation torque on the stance foot is required to change signs during leg swing in order for the pre- and post-impact states to allow for stable limit-cycle walking. This sign-changing torque is implemented by means of a simple control strategy that generates a whip-like gait and allows the biped to walk over irregular terrain and to admit a broad range of initial conditions. Simulations are given including control tuning guidelines for stable walking.
双摆是简单双足机器人的主要机械结构。虽然非常节能,但像指南针一样的步态承受着内在的问题,即在行走时迫使摆动腿的尖端处于地下位置,并且几乎没有地形不规则。本文设计了一种基于双摆的欠驱动双足动物,通过与罗盘步态相反的方向摆动腿来行走。站立脚上的驱动扭矩需要在腿摆动期间改变标志,以便在撞击前后的状态下允许稳定的极限循环行走。这种改变标志的扭矩是通过一种简单的控制策略来实现的,这种控制策略产生了一种鞭状的步态,允许两足动物在不规则的地形上行走,并允许广泛的初始条件。给出了仿真结果,包括稳定行走的控制调谐准则。

Recent developments in the field of electric vehicles have led to a renewed interest in permanent magnet synchronous machines due to its unique characteristics and performance. In this paper, the state of the art of modelling and efficiency mapping techniques for permanent magnet synchronous motors are re-viewed. Then an efficiency mapping test is done experimentally to validate a simple direct-quadrature model. The good correlation obtained from this model, with an error lower than 2% for the majority of the operating points, shows that the model is adequate for representing the behavior of the machine. Future work will be oriented to develop more complex models and to validate simpler experimental parameters determination techniques.

Este trabajo propone un modelo electromecánico no estacionario para simular el comportamiento de propulsores de plasma pulsantes ablativos, con el objetivo de caracterizar el desempeño del propulsor. Además de la ecuación circuital y la ecuación que modela la aceleración de la lámina de plasma, el modelo introduce una ecuación empírica para estimar la masa ablacionada, así como un sistema de ecuaciones basado en la ecuación de Saha, el cual permite modelar la evolución de la densidad del plasma. La introducción de este sistema de ecuaciones requiere de considerar que el sistema se encuentra localmente en equilibrio termodinámico, lo cual se verifica según el criterio de McWhirter. Además, se modela la evolución de la temperatura del plasma mediante la aplicación de la conservación de la energía de la lámina de plasma, considerando el calentamiento por efecto Joule, las pérdidas por radiación y la energía asociada a la fuerza de Lorentz. Al modelo se lo implementa numéricamente, lo que permite estimar parámetros de rendimiento, como la masa ablacionada, el bit de impulso, el impulso específico y la eficiencia propulsiva, entre otros. El modelo ha sido comparado y validado con resultados experimentales de la literatura, demostrando ser capaz de reproducir las variables de desempeño de los APPT dentro de un margen de error del 15 %.
本文提出了一种非稳态机电模型来模拟脉冲烧蚀等离子体推进器的行为,以表征推进器的性能。除了circuital和方程方程建模加快等离子层模型,引入了一个经验公式来估计mass ablacionada以及萨哈方程方程为基础的系统,它能够模拟等离子体密度的变化情况。引入这个方程组需要考虑系统局部处于热力学平衡状态,这是由McWhirter准则验证的。此外,考虑到焦耳加热、辐射损失和与洛伦兹力相关的能量,应用等离子体板能量守恒来模拟等离子体温度的演变。该模型是数值实现的,允许估计性能参数,如烧蚀质量,脉冲位,比脉冲和推进效率等。该模型与文献中的实验结果进行了比较和验证,表明该模型能够在15%的误差范围内再现tpa的性能变量。

This paper studies the temporal evolution, spatial distribution and frequency of occurrence of water-affected surfaces in a typical plain basin of Santa Fe Province (Argentina). The analysis was based on MNDWI time series, obtained from Landsat 8 and MODIS images of the period 2000-2021. By MNDWI thresholding, Open Water and Mixed Water surfaces were identified. In addition, the temporal fluctuation of water-affected surfaces in response to the seasonal cycle of precipitation was explored, which would be influenced by the antecedent water storage. Most of the water-affected surfaces are composed of Mixed Water, Open Water surfaces are made up of certain water bodies with a high frequency of occurrence, located in the lower part of the basin. A sector of accumulation in the upper part coincides with an area of "cañadas". In other sectors of the basin, the surfaces affected by water have low frequencies of occurrence. These results contribute to the knowledge of water dynamics of the study area, and are very useful for the planning and management of the region’s water resources.
本文研究了阿根廷圣达菲省典型平原盆地受水地表的时间演变、空间分布和发生频率。该分析基于2000-2021年期间Landsat 8和MODIS图像获得的mnwi时间序列。采用MNDWI阈值法对开放水面和混合水面进行了识别。此外,还探讨了受水影响面随降水季节周期变化的时间波动,这将受到前期储水量的影响。大部分受水影响的表面由混合水组成,开放水面由某些出现频率较高的水体组成,位于盆地的下部。上部有一个聚集区与“cañadas”区域重合。在盆地的其他部分,受水影响的地表发生频率较低。这些结果有助于了解研究区水动力学,对区域水资源的规划和管理具有重要意义。

Optimización Dinámica del Proceso de Fermentación para la Producción de Xilitol 木糖醇生产发酵过程的动态优化

The following work shows a methodology for the optimization of a fed-batch fermentation process to maximize xylitol production. The bioreactor is fed with two substrates (different streams): xylose and glucose. A technique based on the Fourier series and orthonormal polynomials is proposed for the parameterization of the control actions, and evolutionary algorithms for the optimization of the parameters involved. One of the most obvious advantages of this proposal is that smooth profiles are obtained (continuous and differentiable), using a minimum number of parameters and reaching an increase in the final product concentration of 2.9%.
下面的工作展示了一种优化补料分批发酵过程的方法,以最大限度地提高木糖醇的产量。生物反应器以两种底物(不同的流)为原料:木糖和葡萄糖。提出了一种基于傅立叶级数和正交多项式的控制动作参数化技术,以及参数优化的进化算法。该方案最明显的优点之一是,使用最少数量的参数,获得光滑的轮廓(连续的和可微的),最终产品浓度增加了2.9%。
