Conventional programming of explicit control code is unsuitable for flexible and collaborative production systems. A model-based approach, which focuses on defining capabilities of a system, instead of specifying how to achieve them, provides an alternative for creating complex, scalable, and reliable systems. This is accomplished through the use of behavior models, and tools such as planning, synthesis, verification, and testing. However, developing such models is not without challenges, as it is possible to overlook or incorrectly specify potential behavior and constraints. This can result in unsolvable planning problems or plans that are invalid for other reasons. When plans are unobtainable, developers receive no feedback, which makes model adjustments a difficult and time-intensive task. This paper recognizes these challenges as crucial barriers for adopting model-based development of intelligent automation systems. To facilitate the development of such systems, an approach for detecting and localizing faults in behavior models is presented. Drawing inspiration from software fault localization techniques, the proposed method involves identifying suspicious resources, variables, and operations. The effectiveness of this approach is illustrated with an example use case. © 2023 IEEE.

The problem of confrontation games between multi-agent teams has attracted considerable interest, and the question of how to ensure effective coordination of heterogeneous agents in dynamic and adversarial environments remains a significant challenge. In this paper, we present a decision-making methodology for a confrontation game between two teams, which is based on large language models (LLMs). The game is designed as a competitive Seek-and-Take task comprising three distinct robot types: reconnaissance, grabbing, and blocking robots. The LLMs enhance the robot team’s decision-making efficiency, delivering high-level commands that significantly improve coordination and adversarial performance. The game is initially formalized as a partially observable Markov decision process. Subsequently, a systematic construction of the LLM agents is provided, enabling real-time decisions based on the state information of a heterogeneous robot team (HRT). Detailed prompt design and the "Zero-shot-CoT" procedure are provided, and a cue word iteration method with reflections is proposed as a means of enhancing the decision-making efficiency of the LLMs and generating optimal collaboration strategies. Finally, the efficacy of the methodology is validated through experimentation with multiple LLMs in a multi-robot simulation environment. The results demonstrate that LLMs improve the efficiency and adaptability of decision-making in dynamic environments by serving as a core decision module, generating optimal strategies through real-time analysis. © 2024 IEEE.

Safeguarding high voltage direct current (HVDC) systems against direct current faults is an inherently demanding task. A promising solution to tackle this challenge is the application of piezoelectrically actuated fast mechanical switches (PA-FMS). However, mechanical resonance and random vibrations in the travel curves of P A-FMS have a substantial impact on their control accuracy. To tackle this challenge, a robust-tube model predictive control (RTMPC) strategy is developed. RTMPC drives the disturbed system state into the minimal robustly positively invariant (mRPI) set centered on the target and ensures that constraints are satisfied. The error feedback gain is calculated using the proposed linear matrix inequality (LMI) based method to minimize the effect of disturbances on the trajectory. An efficient outer approximation method is used to compute the mRPI set. Simulation results show that the critically damped travel curves have been achieved, along with a reduction of the external disturbances by 98%. © 2024 IEEE.

Adaptive Generalized Super-Twisting Sliding Mode controller for Wheeled Mobile Robot

IFAC-PapersOnLine 2024年 57卷 345-350页

This paper presents the design of an adaptive generalized super-twisting sliding mode control (SMC) for reference tracking by the two-wheeled mobile robot in the presence of uncertainty. An additional linear correction term is included in the generalized super-twisting control. The designed controller can achieve the convergence of the tracking error and reduced chattering due to the generalized super-twisting structure. The detailed Lyapunov-based stability proof has been derived to ensure the stability of the two-wheeled robot. To relax the dependence on the upper bound of the unknown disturbance, the adaptive SMC has been incorporated. The appropriate adaptive gain has been designed judiciously to ensure the convergence of the sliding variable and the tracking error. Finally, the practical implementation of the proposed adaptive generalized super-twisting robust controller is carried out on a real system, specifically the Q-bot 2e, to illustrate the effectiveness of the designed controller.

Spatial locking of chimera states to frequency heterogeneity in nonlocally coupled oscillators

Chimera states in systems of nonlocally coupled oscillators, i.e., self-organized coexistence of coherent and incoherent oscillator populations, have attracted much attention. In this study, we consider the effect of frequency heterogeneities on the chimera state and reveal that it induces spatial locking of the chimera state, i.e., the coherent and incoherent domains align with lower and higher frequency regions, respectively, in a self-adaptive manner. Using an extended self-consistency approach, we show that such spatially locked chimera states can be reproduced as steady solutions of the system in the continuum limit. Furthermore, we develop a variational argument to explain the mechanism leading to spatial locking. Our analysis reveals how heterogeneity can affect the collective dynamics of the chimera states and offers insights into their control and applications. Copyright © 2025, The Authors.

Humans are now suffering issues because of the rapid growth of the human population. Apart from that, there is a deficiency of appropriate infrastructure in development projects, such as roads and underpasses, which results in a range of challenges, such as water logging and floods. In the event of heavy rain, underpasses and roads get immediately swamped with water, resulting in traffic gridlock and car immobilization. Until recently, there were no planned strategies for monitoring the quantity of water in underpasses and flooded areas, and this is expected to change. We will need to keep a watch on it in the news or on Google Maps, or we will need to find out if anybody else has reported it before. One of the problems with this system is that the information we get moves slowly and easily may be misrepresented or manipulated. The principal aim of this system is to keep track of the quantity of water that is present in underpasses and other flood-prone areas. The data collected by our water level sensor, which we are using to monitor water level, is controlled, and uploaded by an Arduino board equipped with an ESP8266 module. A regular stream of data will be delivered to the cloud, and the vehicle movement will be rerouted in the most suitable way. It follows that individual who are passing via an underpass or on flooded roads may arrange their journeys appropriately by accessing information stored in the cloud. Another feature is the installation of an LCD display near the underpass, which continuously updates the water level, allowing anyone in the neighborhood to determine if it is safe for their car to pass through or not. A DC motor pump is then utilized to pump out the water when the level of the water exceeds a predetermined threshold value. This system has been tested in a number of configurations and has consistently performed as intended and produced dependable results in all circumstances. Furthermore, since it is less costly than prior prototypes, the p

This article presents a method for selecting the best battery sizing based on an optimal market participation strategy in a hybrid renewable power plant. The proposed formulation considers different scenarios to ensure the reserve provision compliance and includes two terms. The first one maximizes the day-ahead and automatic frequency restoration reserve (aFRR) market revenues. The second minimizes the battery degradation, accounting for both cycling and calendar ageing effects. The Iberian Electricity Market is selected as the study case, and two different market scenarios are compared: the current market scenario and the upcoming one, in which the upward and downward aFRR band offers are independent. The operation of a set of batteries is simulated until their end of life, and results reveal that energy/power ratios higher than 3 h for the current market scenario, and than 4 h for the upcoming one, are less cost effective. Regarding the best battery energy storage systems sizing, the selection varies considering incomes or profitability criteria. Moreover, keeping the current prices, in the upcoming market scenario hybrid renewable power plants are encouraged to participate more in the downward than in the upward aFRR market. © 1972-2012 IEEE.
