This work presents the architecture and development of the Serious Game (SG) Memô which is aimed at exercising the Short-Term Memory (STM) of children with Autism Spectrum Disorder (ASD). This serious game proposes an individualized functional approach through Dynamic Difficulty Adjustment (DDA), which considers the performance, the expressed facial emotions, and the level of eye attention during child performance. In addition, it is used to recording the presence of hand and eye stereotypies. The SG is developed in Unity 3D, uses MediaPipe to determine the points of the hands, and is executed by our Socially Assistive Robot (SAR), termed Mobile Autonomous Robot for Interaction with Autistics and Trisomy 21 (MARIA T21). We believe that the creation of SGs to assist in the cognitive development of children with ASD and explore the detection of other stereotyped movements, associating them with a communicative and emotional proposal, is feasible. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.

In the field of electric vehicles, the safety of power lithium-ion batteries is a socially important issue, and the study of thermal runaway of lithium batteries is now gradually becoming more in-depth. In this paper, the output parameters are up-dimensioned. Using a global sensitivity analysis method based on the Moms screening method, the influence of 11 parameters such as volume of the cell(vBt), mass of the cell(mBt) and electrolyte concentration (W_e) on the thermal runaway process of Li-ion batteries is analyzed, and the variation of 10 variables such as temperature(T) and carbon dioxide gas (CO2) produced in the thermal runaway side reaction heat generation process and chemical reaction gas generation process over time is investigated under the influence of the parameter factors. In the study, the sensitivity of the parameters over a time interval is investigated in the rising dimension of the time domain. The results show that the overall effect of the parameters on the thermal process;for the output variables of the thermal process, they are mainly affected by the mass of the cell (m_Bt), the thickness of the SEI film (t_sei) and the specific heat capacity of the cell(Cp_Bt), while the chemical process is not significantly affected by the different parameters;among all the parameters, the volume (V_Bt) of the cell interacts most strongly with the other parameters for all the output variables. Finally, the results of the sensitivity analysis of the thermal runaway side reactions of the battery will be applied to the subsequent 3D simulation study. © 2023 IEEE.

An H∞ Load Frequency control Scheme for Multi-Area Power system Under Cyber-Attacks and Time-Varying Delays

引用

IEEE Transactions on Power systems 2023年第2期38卷 1336-1349页

作者： Zhang, Guangdou Li, Jian Bamisile, Olusola Xing, Yankai Cai, Dongsheng Huang, Qi University of Electronic Science and Technology of China Power System Wide-Area Measurement and Control Sichuan Province Key Laboratory School of Mechanical and Electrical Engineering Sichuan Chengdu610056 China Chengdu University of Technology College of Nuclear Technology and Automation Engineering Sichuan611400 China

In the power system, the application of the signals transmitted from the sensors to the controller can significantly improve the dynamic performance. However, cyber-attacks and time delays exist widely in the communication network, which has a considerable effect on stability, operation, and control. In this paper, an ${{\boldsymbol{H}}_\infty }$ load frequency control (LFC) scheme for multi-area power systems under cyber-attacks and time-varying delays is investigated. First, false data injection attacks (FDIA), as well as denial of service (DoS) attacks, are viewed as two typical cyber-attacks and introduced into the multi-area power system. Then, the state-space equations of the LFC power system under these two attacks and time-varying delays are analyzed and modeled. Furthermore, by using Lyapunov stability theory and linear matrix inequality (LMI) method, an ${{\boldsymbol{H}}_\infty }$ LFC scheme for attacked and delayed power systems is developed. The purpose of the proposed controller is to guarantee the closed-loop system exponentially mean-square stable with prescribed ${{\boldsymbol{H}}_\infty }$ performance. Finally, a three-area LFC system is employed to demonstrate the effectiveness of the proposed mechanism. The simulation results verified that the control performance of an attacked and delayed system can be improved significantly via the designed controller. © 1969-2012 IEEE.

This paper presents investigations of a transformerless half bridge sub-module (HBSM) modular multilevel converter based distribution static synchronous compensator (MMC D-STATCOM) performance in reactive power compensation considering the application of the modified ADRC controllers in the inner current loop and in the outer DC voltage loop using Synchronous Reference Frame control. Simulation results with the imposition of severe variations in reactive loads were obtained on a 5 km medium voltage feeder and will demonstrate that the modified ADRC controller enables superior performance for flexible operation with fast and efficient response of the MMC D-STATCOM in reactive power compensation. © 2023 IEEE.

Much of the data obtained by health professionals for diagnosis and therapies applied to children with Autistic Spectrum Disorder (ASD) and Down Syndrome (DS) depend on visual observations and interviews with family members and clinical assessments. Therefore, the use of sensors has the potential of complementing this process by generating quantitative data. This work demonstrates that the use of sensors embedded in a Socially Assistive Robot (SAR) developed at UFES/Brazil, termed Mobile Autonomous Robot for Interaction with Autistics and Trisomy 21 (MARIA T21), can be used as a centralized tool to quantify more objective measures of children’s spatial, postural and social behavior during the interaction with the robot through Serious Games (SG) projected on the floor by the robot. The information generated can help therapists in the application of more efficient therapies, as well as monitor the evolution of the children submitted to the protocol with the robot. The results demonstrates the feasibility of using these sensors and evidence the requirements to be evolved. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.

This paper presents the dynamic modelling and end effector position control of a soft endoscope. Soft endoscope system under study consists mainly of a pneumatic driven soft actuator (PDSA) with four independently chambers. Recurrent neural network (RNN) and dynamic back propagation (DBP) training algorithm are used to obtain PDSA dynamic model. PDSA position controller is based on a feedforward neural network (FNN) and it is trained using PDSA closed loop system (CLS) and DBP training algorithm. CLS stability analysis concludes that it is not possible control PDSA end effector position using one position controller for different end effector initial and desired positions. Fuzzy logic methodology is used to integrate several positions controllers in a one controller valid for all operation range. The controller implementation and close loop system simulation are performed in MATLAB for different end effector desired position to validate system performance in all range of operation. © 2024 IEEE.

Cloud-based energy management systems (EMS) in smart grids face privacy challenges, as existing methods based on traditional homomorphic encryption support limited operations and are vulnerable to quantum attacks. We propose a privacy preservation method for smart grid energy management system, leveraging edge-assisted computing and ring learning with errors (RLWE) homomorphic encryption. Our approach enables both addition and multiplication operations on encrypted smart grid data while defending against quantum threats. We demonstrate the methods security under the RLWE hardness assumption and validate its effectiveness through an experimental platform simulating smart grid environments. This work addresses computational limitations in current privacy-preserving techniques, enhancing data security for evolving smart grid technologies © 2010-2012 IEEE.
