This paper presents the three phase modified bridgeless Vienna rectifier for electric vehicle (EV) charger. This topology has significant impact on power quality improvement such as power factor improvement. The modified topology is more advantageous in automotive industry. The EV charger developed using this technique is compact and economical. The DC bus voltage controlled in the designed Vienna rectifier is achieved through adaptive sliding mode controller (smc) controller. The adaptive smc controller is designed by incorporating the characteristics of internal model controller (IMC). This DC voltage control enables the control on charging of EV and battery. This adaptive smc controller enhances the sinusoidal tracking performance and also reduces the steady state error. The proposed adaptive smc controller also ensures the stability of the system. The proposed system is verified in simulation and the results are validated through comparison with smc controller. The results are validated through power factor improvement in modified smc. © 2024 ieee.

Nowadays, Heat exchanger systems are commonly employed in chemical plants due to their ability to maintain temperature and pressure within a broader range. The system transfers heat between two mediums while preventing them from mixing. It controls the liquid temperature inside closed processes, including large industrial systems. The problem encountered by heat exchanger systems is that they are prone to external effects like fluctuations in the surrounding temperature. These effects may disturb the system and lead to unsatisfactory results. This paper presents a solution to eliminating disturbances and noise signals, thus producing better results. Initially, a traditional PID controller was integrated into the system. The result obtained was different from what was expected. Then, the solution was sought in another controller, namely the sliding mode controller (smc). smcs have been found to work better than PID controllers, especially with non-linear systems, and they do not rely on system parameters. An smc was designed and added to the system based on its advantages over PID controllers. The developed smc showed better overshoot and settling time results than the classical controller. The system's response was improved, and the disturbances were eliminated. The design and evaluation of the controller were carried out using MATLAB Simulink software. © 2024 ieee.

Cyber-physical systems (CPSs) are a kind of systems integrating cyber and physical components, which may be subject to physical uncertainty and cyber interference in the process of operation. In order to solve this problem, a new control design method is proposed by studying the constrained following problem of controlled systems under physical uncertainty and cyber interference. The remarkable feature of this control is that both physical uncertainty and cyber interference are taken into account, which ensures that the controlled system can resist cyber interference while still meeting the expected constraints. In addition, the effectiveness and superiority of the proposed control method are verified by the simulation comparison with sliding mode control (smc) in the autonomous vehicle scenario.

Marine accidents often result from errors in situation awareness (SA) among navigators. Despite the ongoing unmanned ship projects worldwide, the implementation of unmanned systems on many ships is expected to take a considerable amount of time. Therefore, the support technology for shipboard navigators and maritime autonomous surface ship's operators will continue to be crucial in the future. Additionally, to address the challenges posed by the shortage and aging of seafarers, supporting the SA of beginner navigators is essential. In this study, we propose a support system for enhancing the SA of beginner navigators using voice information. This system aims to encourage the gathering of information on target ships and, if necessary, prompt actions against target ships. The results of simulator experiments with cadets, using the Situation Awareness Global Assessment Technique demonstrated the effectiveness of the proposed support system in enhancing SA and decision-making among beginner navigators through voice information. However, to enhance the practicality of the system, it is essential to adjust the timing, contents, and frequency of the voice information according to the skill levels of beginner navigators. © 2024 ieee.

As robot surgery becomes more popular these days, it consequently solicits a high demand on its training system. Currently, most of the systems are intended for personal training, while it may be more effective if an experienced expert can also be involved. It thus motivates us to propose a dual-user robotic surgical training system that can closely link the mentor and trainee together. The system is developed in a mixed-reality environment that integrates the information from both the virtual and real worlds. The haptic feedback and virtual fixtures are employed for assistance during skill transfer. The proposed system can assess the proficiency level of the trainee for the mentor to provide proper assistance during training. The experimental results demonstrate that the proposed system is capable of enhancing the trainee's ability for surgery. Especially, similar effectiveness is observed during comparative studies with direct hands-on guidance frequently adopted for skill transfer during sport training. © 2024 ieee.

We have developed HEARTS, a dementia care training system using augmented reality based on Humanitude. Humanitude is a multimodal comprehensive care technique for dementia, and has attracted attention as a method to reduce the burden on both caregivers and patients. However, the HEARTS developed so far could not evaluate 'speaking' skills based on the content of conversations among 'seeing,' 'touching,' and 'speaking,' all of which are fundamental skills in Humanitude. Therefore, we attempted a new quantitative evaluation of trainees' 'speaking' skills by estimating the emotional value of conversational content using GPT-4 named HEARTS 5. A survey of caregivers was conducted using the developed system and was well received by the participants. We also developed a HEARTS 5 conversational version based on HEARTS 5, with the addition of GPT-4 conversation generation and Azure Text-to-Speech. © 2024 ieee.

Human activity prediction has become increasingly prevalent in a plethora of time-critical applications. To realize accurate identification and prediction of human behaviour, we propose a situation-aware wearable computing system. A wearable computing system has the capability to perceive, comprehend and project situations by analyzing the human behavioral patterns in different environments. In particular, this work proposes a situation-aware human activity prediction (SA-HAP) approach based on sequential pattern mining that aims to anticipate future activities and tailor its responses according to situations by analyzing frequent sequential patterns and their correlations to understand how these situations are interrelated. The approach not only improves prediction accuracy but also provide the foundation for a more informed decision-making process, as the projected situations can be explained using the identified behavioral patterns. The approach is compared with other traditional techniques for activity prediction (LSTM and HMM), achieving better performance on the Extrasensory dataset. © 2024 ieee.

This paper, presents the quadcopter's dynamic modeling using the Newton-Euler formalism and a sliding mode controller with backstepping (smcBS) to achieve stabilization of the quadcopter. In the paper uses a PSO (Particle Swarm Optimization) technique to optimize the smc gains that objective is to enhance the tuning process and attain optimal outcomes. The evaluation measures, such as ITAE (Integral of Time multiplied by Absolute Error), IAE (Integral of Absolute Error), and ISE (Integral of Squared Error) provide evidence of the PSO algorithm's efficacy in stabilizing and monitoring the quadcopter's trajectory. The results show that the PSO-smcBS controller better performs under wind-disrupt environment in comparison to the smc and smcBS controllers.

In this study, we address the secure model predictive control (MPC) problem for a system comprising unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs). Our objective is to cooperatively regulate the UAV -UGV system to maintain all states at equilibrium in spite of physical constraints, external disturbances, and Denial of Service (DoS) attacks on communication channels. We propose a dynamic event-triggered distributed MPC (DET-DMPC) approach. Initially, a robustness constraint is integrated into the MPC to incrementally confine system states within a progressively narrowing tube, thereby bolstering disturbance resilience. Additionally, we introduce a neighbor output sequence prediction mechanism (NOSPM) to mitigate packet loss due to DoS attacks. In response to the varying durations of DoS attacks, we have developed a DET mechanism equipped with adaptive triggering thresholds. Moreover, we have formulated sufficient conditions that ensure the recursive feasibility of the DMPC algorithm and the stability of the UAV-UGV system. Comparative tests demonstrate the proposed DET-DMPC's superiority in robustness and security. © 2024 ieee.
