Heat pumps can play a crucial role in the European energy strategy 2050, which aims to achieve net-zero greenhouse gas emissions. When coupled with thermal energy storage and integrated with advanced control strategies, heat pump operation can be optimized to reduce carbon footprint and respond to the needs of system operators. However, to scale in a multitude of buildings, the transferability of the modeling into heterogeneous systems is crucial. In this paper, two different interpretable linear models, a hybrid (grey-box) and a fully data-driven (black-box) model are investigated. Specifically, two regression-based identification methods (SINDYc and DMDc) are used for dynamic models and the LASSO regression is used for static models. The transferability of the approach is evaluated using two real-world facilities with heterogeneous sizing and configuration. The results show a similar simulation performance for both cases with a maximum normalized RMSE of 0.41 and 0.60, respectively. This confirms the transferability of the approach that is necessary for large-scale implementation. © 2023 Institute of Physics Publishing. All rights reserved.

Based on the set coverage theory and the multi-objective site selection planning theory, a multi-objective site selection planning model for rescue trains of a railway in mountainous area of China is established. The results show that when four rescue trains are planned to be deployed, two schemes can be obtained, and the average rescue response time of the two schemes is not much different. When five rescue trains are planned to be deployed, five schemes are obtained, of which the average rescue response time of four schemes is very close, and they can be considered as reasonable schemes. When six or more rescue trains are planned to be deployed, the deployment density of rescue trains is too high, resulting in redundancy of rescue resources. Compared with the single objective site selection planning model, the scheme obtained by the multi-objective site selection planning model of the railway in mountainous area of China rescue train can greatly reduce the average rescue response time and improve the rescue efficiency. © ASCE.

The single phase H6 topology inverter has the advantages of simple structure, small common-mode leakage current, low current distortion rate and high security, which is very suitable for small distributed photovoltaic power generation system. In terms of suppressing the power grid harmonics of H6 topology photovoltaic inverter, there have been many studies both at home and abroad. For example, traditional PI control has simple algorithm and fast tracking speed, but poor steady-state performance. Repetitive control has good steady-state performance, but the tracking has one cycle lag. In this paper, the harmonic suppression design of voltage controller with notch filter is introduced. Moreover, the simulation and experimental test of designed controller is provided to validate the voltage controller with notch filter for H6 topology inverter has obvious effect on harmonic suppression. © 2022 IEEE.

The Internet of Things refers to the type of network that connects anything to the Internet on the basis of the protocols stipulated by the information sensing equipment for the exchange of information and communication in order to achieve smart recognition, positioning, tracing, monitoring and administration. Movable harbor crane (MHC) is a major part of logistics services. Logistics is the management of the flow of goods between the point of origin and the point of consumption in order to meet the requirements of customers or corporations. MHC is mainly used for the loading and unloading of ships. This paper presents recommendations and practices to be used in the future of the smart industry internet (IoSI) and explores the different applications of smart sensor networks in the movable harbor crane. The main objective of the current paper is to develop a conceptual framework for monitoring and controlling harbor movable crane using a cloud on the IoT-PLC control system. Experimental results show that the proposed system is applicable and effective. © 2021 IEEE.

The interaction between various energy supply systems (cold, heat, electricity, gas, etc.) is becoming more tightly coupled as social economy and technology advance. Multi-energy systems are ineffective because different types of energy systems run independently. In order to protect the data privacy of each sub-system, this research suggests an ideal resource management framework for a multi-energy group control system. The energy hub (EH) paradigm is first suggested. When deploying EHs, the physical constraints of various energy systems are taken into account. Through scenario-based stochastic programming, the uncertainties of renewable energy are considered. According to the leader-follower relationship between multi-energy group control system operators and energy hub operators (EHOs), Benders decomposition is applied to decentralize the decision-making process. Finally, an example is given to illustrate the effectiveness of the proposed model and algorithm. © 2023 IEEE.

Securing Mobile Robotic Networks Against Replacement Attack

IEEE Transactions on Automatic control 2025年第7期70卷 4424-4438页

The security of mobile robotic networks (MRNs) has been an active research topic in recent years. This paper aims to secure the ubiquitous formation control of MRNs against the replacement attack, where an external robot can replace a formation robot by compromising the communication and physically interfering with the victim simultaneously. To counter this advanced attack, the novel idea of this work is to leverage the physical proximity of the formation shape and the interaction topology among robots for defense design. First, from the physical proximity perspective, we propose the convex neighbor polygon (CNP) to capture the geometric characteristic of the formation robots, and design a CNP-based security mechanism for the robots during the replacement attack. Then, from the interaction perspective, we introduce the indirect controllability to characterize the possibility that the attacker leverages the interaction between robots to deactivate the CNP mechanism, and establish the conditions regarding the topology structure and the attack input to counter the replacement. Finally, based on the obtained conditions, we demonstrate how to design the initiatory topology among the formation robots to enhance the defense performance. Comparative simulations verify the effectiveness of the proposed method. © 1963-2012 IEEE.

On Optimal Synchronization of Diffusively Coupled Heterogeneous Van der Pol Oscillators

This paper proposes a novel method to achieve and preserve synchronization for a set of connected heterogeneous Van der Pol oscillators. Unlike the state-of-the-art synchronization methods, in which a large coupling gain is applied to couple any pair of connected oscillators, the proposed method first casts the whole synchronization process into two phases. The first one considers the period from the beginning to the first instant of synchronization, while the second phase covers the following time in which synchronization must be preserved. It is shown that a large coupling gain is adopted for the first phase, while the averaged coupling gain to preserve the synchronization in the second phase can be reduced significantly by using an offline optimized coupling law. Efficiency and performance of this method are confirmed by a set of numerical tests with different graphs and system dynamics. © 2023, CC BY-NC-ND.

An MPC controller is proposed to maximise the use of renewable energy in a manufacturing process. The strategy has been applied in a manufacturing system which has several machines, renewable generation resources, a combined heat and power (CHP) generator for power production, and a battery bank for energy storage. The work aims to maximise the use of renewable energy sources in this process, also taking into account the price of the electricity market, to reduce the cost. The use of neurofuzzy models for the prediction of the energy produced by renewable generators allows a dynamic prediction, using input values obtained from typical forecasting variables (wind speed, global irradiance, etc.).

Centralized systems that require third parties remain opaque and represent a single point of failure. Therefore, in accordance with the requirements of cloud services and identity management mechanisms, it is necessary to move towards more transparent and collaborative methods. That is, all service providers under the same federation deal positively with the issued identity of the user. The distributed format gives good potential for ID management systems and treats everyone with the same level of validity. This paper presents a blockchain-based identity management system for the purpose of creating a federated identity management system that is used by multiple organizations by Taking advantage of decentralization and high transparency in the blockchain. Several vital advantages of blockchain are positive for forming identity management systems characterized by transparency and high security, and privacy. Implementing the proposed system on a private Hyperledger Fabric blockchain network proved effective according to the criteria studied, and there is also great potential for improvement. The practical application of the proposed system proved high quality and promising possibilities in blockchain based identity management.

The study presents a methodology for automatically creating an annotated dataset for further use in training neural networks. The method is based on the Crisp-DM framework and consists of 6 stages: business understanding, data understanding, data preparation, modeling, evaluation, deployment, which has been modified due to the specifics of computer vision tasks. As a modeling method, the k-means method is proposed, which is applied to the normalized area and average color data of a given object. The approach is tested for creating an annotated dataset for recognizing and localizing cells of different types in blood smear images. The output is a dataframe with the columns file_name, xmin, ymin, xmax, ymax, type, area, which represent the file name, the coordinates of the upper left and lower right points of the bounding boxes, the cell type, and its area. Using these parameters and image processing libraries it is easy to add bounding boxes to the original images. The resulting annotated dataset is analyzed. Metrics were calculated and a loss matrix was constructed. All calculations were performed using the Python programming language and the Pandas, numpy, openCV, and matplotlib libraries.
