This article proposes the use of a proportional–integral–derivative (PID) controller as an adaptive mechanism within the framework of the model reference adaptive system-based rotor flux (MRASF) for accurate rotor speed estimation in induction motors. The controller is designed to impose specific dynamic behaviors and performance criteria, addressing the sensitivity of MRASF dynamics to slip speed. To achieve this, a full-order transfer function of the MRASF is employed to systematically derive the PID parameters using compensation and pole placement techniques. The proposed control strategy ensures that the estimated rotor speed closely follows the desired performance across various operating conditions. The effectiveness of the MRASF–PID design is validated through both simulation and experimental testing under open-loop voltage/frequency control of the induction machine, confirming the successful realization of the targeted dynamic and steady-state performance.
本文提出在基于模型参考自适应系统的转子磁链(MRASF)框架内使用比例-积分-导数(PID)控制器作为自适应机制来精确估计异步电动机的转子转速。该控制器旨在施加特定的动态行为和性能标准,解决MRASF动力学对滑移速度的敏感性。为了实现这一目标,采用MRASF的全阶传递函数,利用补偿和极点放置技术系统地导出PID参数。所提出的控制策略保证了在各种工况下转子转速的估计值接近期望性能。通过在感应电机开环电压/频率控制下的仿真和实验测试,验证了MRASF-PID设计的有效性,确认了目标动态和稳态性能的成功实现。

Mismatched operating conditions occur very frequently in photovoltaic arrays, especially in urban installations or those that are commonly referred to as agrivoltaic. Mismatches are not only due to partial shading, but also to modules’ construction tolerances and installation mistakes, to maintenance operations, to a different effect of aging on modules, to an uneven distribution of dust, pollution, and snow on the module surfaces. The simulation of photovoltaic arrays operating in mismatched conditions is required in many applications, from plant design to model-based control, from monitoring and diagnosis up to the implementation of a digital twin. Some applications require not only an extreme granularity level (even at the single cell or fractions of it) but also a very fast computation compatible with real-time applications, running on embedded processors. This article introduces a new approach to the simulation of mismatched photovoltaic arrays based on isomorphism. The approach exploits similarities among subsections of the array to minimize the number of nonlinear equations modeling it. The lower the simulation accuracy required, the smaller the rank of the system of equations to solve. The application examples proposed in the article, concerning a PV array affected by a partial shading by nearby objects that changes during the day and a faulty PV field made up of half-cut modules, allow one to quantify the reduction in model complexity and the consequent computation time granted by the proposed technique as a function of the desired accuracy of the simulation results.
在光伏阵列中,特别是在城市装置或通常被称为农业光伏的装置中,经常发生不匹配的操作条件。不匹配不仅是由于部分遮阳,还包括模块的施工公差和安装错误,维护操作,老化对模块的不同影响,以及模块表面灰尘,污染和雪的不均匀分布。从电站设计到基于模型的控制,从监测和诊断到数字孪生的实现,许多应用都需要在不匹配条件下运行的光伏阵列的仿真。一些应用程序不仅需要极端的粒度级别(即使是单个单元或部分单元),而且还需要与运行在嵌入式处理器上的实时应用程序兼容的非常快的计算。本文介绍了一种基于同构的不匹配光伏阵列模拟新方法。该方法利用阵列的子部分之间的相似性来最小化非线性方程建模的数量。仿真精度要求越低,需要求解的方程组的秩就越小。本文中提出的应用示例,涉及受白天变化的附近物体部分遮阳影响的光伏阵列和由半切割模块组成的故障光伏场,允许人们将模型复杂性的降低和由此产生的计算时间量化为模拟结果所需精度的函数。

This article introduces the implementation of an adaptive termination impedance alongside a corresponding control algorithm designed for resonant arrays in inductive wireless power transfer systems for vehicle charging applications. The integration of an adaptive termination impedance in the final cell of the array significantly improves both energy transfer between the transmitter array and the receiver. By employing the proposed algorithm, which estimates the receiver’s position relative to the array through voltage and current measurement in the first cell directly connected to the power source, the need for additional position sensors is eliminated. Moreover, this innovative approach not only reduces the number of components but also lowers system cost and complexity, while allowing the system to be modular, as the proposed method works for any number of array cells. The effectiveness of the proposed solution has been validated through comprehensive simulations and experimental testing.
本文介绍了一种自适应终端阻抗的实现以及相应的控制算法,该算法是为汽车充电应用的感应无线电力传输系统中的谐振阵列设计的。在阵列的最后一个单元中集成自适应终端阻抗显著改善了发射阵列和接收器之间的能量传递。该算法通过直接连接到电源的第一个单元的电压和电流测量来估计接收器相对于阵列的位置,从而消除了对额外位置传感器的需求。此外,这种创新的方法不仅减少了组件的数量,还降低了系统成本和复杂性,同时允许系统模块化,因为所提出的方法适用于任何数量的阵列单元。通过综合仿真和实验测试,验证了该方案的有效性。

This article presents a method to detect and classify series arc faults affecting domestic AC electrical circuits by the analysis of electric current time series data, based on the HYDRA (HYbrid Dictionary-Rocket Architecture) algorithm, a fast dictionary method for time series classification employing competing convolutional kernels. The key novel contributions are twofold: Competing convolutional kernels are suitable to effectively extract features representing an effective set of arc fault detection indicators, and the classification performed in this way is feasible to be executed in real time. The proposed method is validated using a public database, where data from 13 different types of loads is collected according to the IEC 62606 standard. To reduce inference time and optimize the algorithm for embedded control units, a feature reduction strategy is employed. The effectiveness of the proposed method is demonstrated through experimental tests conducted under both arcing and non-arcing conditions and across different load types. Moreover, its accuracy is also tested in case of transients caused by operational changes in common electrical appliances. Achieved results show a detection accuracy of approximately 99%, with appliance classification performance around 98%, with inference times ranging from 2.8 to 172.0 ms while executing the algorithm on an ARM Cortex-based board.
本文提出了一种基于HYDRA (HYbrid dictionary - rocket Architecture)算法的基于竞争卷积核的时间序列快速字典分类方法,通过对电流时间序列数据的分析,对影响国内交流电路的串联电弧故障进行检测和分类的方法。关键的新贡献有两个:竞争卷积核适合于有效地提取代表一组有效电弧故障检测指标的特征,并且以这种方式执行的分类是可行的,可以实时执行。使用公共数据库验证了所提出的方法,该数据库根据IEC 62606标准收集了来自13种不同类型负载的数据。为了减少嵌入式控制单元的推理时间并优化算法,采用了特征约简策略。通过在电弧和非电弧条件下以及在不同载荷类型下进行的实验测试,证明了所提出方法的有效性。此外,在普通电器操作变化引起的瞬变情况下,也测试了其准确性。实现的结果表明,在基于ARM cortex的电路板上执行该算法时,检测精度约为99%,设备分类性能约为98%,推理时间范围为2.8至172.0 ms。

Internet of Things (IoT) driven digitalization is shifting data processing to the edge, reducing the burden of constant cloud communication. Advances in resource-constrained microcontroller-based IoT devices that interact with the environment, such as in cyber-physical production systems, enable them to assist in computation offloading, extending edge computing into the so-called far-edge that includes such devices. However, updating these devices often requires manual interventions, full firmware updates, or proprietary tools, leading to potential application downtime. To fully leverage far-edge enhanced computing capabilities, it is crucial to integrate far-edge devices with cloud orchestration tools, streamlining service management and deployment along the cloud to the far-edge continuum. Current approaches overlook these devices’ computing power and their potential to host services, supporting IoT continuum orchestration only from the cloud to the edge. This article introduces far-edge IoT device management (FITA), the first platform that integrates far-edge devices into Kubernetes-based infrastructures. FITA provides a far-edge container-like solution compliant with the open container initiative. It extends Kubernetes to support service deployment on heterogeneous far-edge devices seamlessly and provides a method for creating virtual representations of far-edge devices to expose their unique capabilities to the Kubernetes scheduler. Our evaluation shows a mean deployment time on clusters with 500 services and 100 devices of around 600 ms, and a device registration time of around 1080 ms, with CPU and memory consumption of around 23 milicores and 1500 MB, respectively. Overall, FITA improves service continuity, deployment speed, and application resilience, supporting the future of the IoT, particularly in industry.
物联网(IoT)驱动的数字化正在将数据处理转移到边缘,减少持续云通信的负担。资源受限的基于微控制器的物联网设备与环境交互,例如在网络物理生产系统中,使它们能够协助计算卸载,将边缘计算扩展到包括此类设备的所谓远边缘。然而,更新这些设备通常需要人工干预、完整固件更新或专有工具,从而导致潜在的应用程序停机。为了充分利用远端增强的计算能力,将远端设备与云编排工具集成,简化服务管理和沿着云到远端连续体的部署是至关重要的。目前的方法忽略了这些设备的计算能力及其托管服务的潜力,只支持从云到边缘的物联网连续编排。本文介绍了远边缘物联网设备管理(FITA),这是第一个将远边缘设备集成到基于kubernetes的基础设施中的平台。FITA提供了一种与开放容器计划兼容的边缘容器解决方案。它扩展了Kubernetes,以无缝地支持异构远端设备上的服务部署,并提供了一种方法来创建远端设备的虚拟表示,从而将其独特的功能暴露给Kubernetes调度程序。我们的评估显示,在拥有500个服务和100台设备的集群上,平均部署时间约为600毫秒,设备注册时间约为1080毫秒,CPU和内存消耗分别约为23毫秒和1500 MB。总体而言,FITA提高了服务连续性、部署速度和应用弹性,支持物联网的未来,特别是在工业领域。

Industrial edge computing provides new possibilities for traditional industrial automation systems. With massive computing, storage, and communication resources equipped with devices on the shop floor, a typical edge device can simultaneously handle multiple real-time and non-real-time tasks. Also, those tasks may include operation technologies, such as real-time control, and information technologies, such as data processing. Using a generic modeling language to design those new industrial edge applications becomes a challenge for site engineers. This paper proposes the IEC 61499 standard for operation and information technology convergence for industrial edge applications. The concurrent execution semantics of IEC 61499 function blocks are defined to support multiple applications simultaneously. The event scheduling rules are investigated to ensure the determinism of parallel executions of function block networks. Finally, a case study is provided for the performance analysis of the proposed concurrent execution semantics.

In this article, a new type of self-powered active mass damper (SPAMD) based on permanent magnet synchronous motor is designed for large-scale flexible structure vibration reduction systems. SPAMD can fully utilize the characteristics of four-quadrant operation of the motor, enabling active suppression of structural vibration while recovering energy. To achieve active vibration reduction control, a distributed control strategy of multiple energy-interconnected self-powered active mass dampers is proposed. Therein, a multilevel substructure method is employed to allocate actuators across different levels of the substructure systems. In addition, a distributed economic model predictive control (DEMPC) strategy is presented to optimize control inputs, which can ensure that the flexible structural system achieves optimal energy recovery power while satisfying certain state constraints. Consequently, the coordinated control of system performance and energy recovery is achieved under self-powered conditions. Extensive experiments on the dSPACE DS1006 platform are carried out to verify the feasibility of the proposed DEMPC method.
针对大型柔性结构减振系统,设计了一种基于永磁同步电机的自供电主动质量阻尼器(SPAMD)。SPAMD可以充分利用电机的四象限运行特性,在回收能量的同时主动抑制结构振动。为实现主动减振控制,提出了一种多能量互联自供电主动质量阻尼器的分布式控制策略。其中,采用多级子结构方法在子结构系统的不同层次上分配作动器。此外,提出了一种分布式经济模型预测控制(DEMPC)策略,对控制输入进行优化,使柔性结构系统在满足一定状态约束的情况下达到最优能量回收功率。从而实现了自供电条件下系统性能与能量回收的协调控制。在dSPACE DS1006平台上进行了大量实验,验证了所提出的DEMPC方法的可行性。
