Critical boundary scenarios play a vital role in the comprehensive testing of autonomous vehicles, as they can significantly expedite testing processes and reduce economic and time costs. To tackle the intricate, multidimensional, and diverse nature of intelligent driving scenarios, this paper proposes an innovative bi-level adaptive deep reinforcement learning (BADRL) approach aimed at generating authentic and diverse critical boundary scenarios. Leveraging naturalistic driving data, background agents are trained to exhibit naturalistic and realistic driving behaviors using a neural-based naturalistic driving behavior model. To address the intricacies of multi-interaction, high-dimensional environments, the scenario complexity model is introduced to evaluate the relative complexity between the traffic environment and the tested autonomous vehicle in real time. By integrating the scenario complexity model, the naturalistic driving behavior learning, intelligent driving testing, and critical boundary scenario generation are concatenated together to form a closed loop. BADRL facilitates the upper-level neural network in learning to adaptively increase the complexity of test scenarios, which are then fed into lower-level models to optimize the behavior of principal traffic participants, thereby generating naturalistic and critical boundary test scenarios. Extensive simulations were carried out to verify the efficacy of the BADRL technique in complex intersection environments. Results indicate that the BADRL approach boosts the efficiency of critical boundary scenario generation by approximately 10% compared to the state-of-the-art method. © 2024 Technical Committee on control Theory, Chinese Association of Automation.

This paper focuses on the tracking problem of a perturbed wheeled mobile robot(WMR). Taking both the kinematic model and dynamic model into account, a transformed model is proposed based on the heading position. By extracting deep-root information from the lumped disturbance, the influence of the lumped disturbance can be estimated and eliminated by a simple adaptive compensation term. concurrent learning(CL) is introduced to the adaptive law to relax the persistent excitation(PE)condition. A Lyapunov-based method is used to ensure globally uniformly ultimately bounded(GUUB) stable tracking. The proposed control strategy is proven effective by a numerical simulation.

This paper aims to study the output feedback control for multi-agent systems under dynamic event-triggering mechanism. First, a new dynamic output feedback control law is developed by using the relative outputs between neighboring agents at triggering time instants. Compared with existing work, this control protocol does not require interaction between controllers. Second, a dynamic event-triggering mechanism is designed, which effectively reduces the amount of data transmission between agents. Events are mainly triggered during initial periods when the system has not achieved consensus, and each agent will not show Zeno behavior when intensive triggering is required. Finally, the effectiveness of the developed control protocol under dynamic event-triggering mechanism is verified by a numerical simulation.

In recent years, the rapid advancement of electric vehicles has heightened concerns regarding the safety of high-energy batteries. Consequently, there has been a significant focus on the development of fault diagnosis technologies for batteries. Intelligent fault diagnosis (IFD), particularly data-driven approaches, represents a crucial methodology in addressing this concern. This paper proposes a data-driven approach, for IFD in high-energy batteries utilized in electric vehicles. The proposed Exponentially Weighted Average Variational Mode Decomposition (EWVMD) method overcomes these limitations by employing the exponential weighted moving average (EWMA) technique to smooth collected time-series voltage data. This process reduces noise, accentuates abnormal change trends, and yields secondary data with enhanced features. Subsequently, variational mode decomposition (VMD) is applied to the secondary data. The resulting decomposed sub-mode curves (intrinsic mode functions - IMFs) and the change trends of the residual curve, in conjunction with a fault threshold tailored to actual working conditions, are utilized to ascertain the occurrence of faults. Design verification experiments, the C42MSA electric vehicle power supply battery undergoes charging and discharging tests with injected faults at fixed intervals. The collected fault signals are then subjected to fault diagnosis using EWVMD. Results demonstrate the algorithm's superior detection effectiveness and increased sensitivity to fault signals compared to traditional methods. © 2024 IEEE.

This paper presents a concurrent estimation method for a polynomial kernel-based nonlinear observer canonical model with a generic structure for nonlinear systems. The algorithm alternates the separable least squares parameter estimation algorithm and extended Kalman filtering. It has the characteristic of fast convergence to a local optimum which depends strongly on the initial values of parameters. To improve its convergence to the global optimum, a genetic algorithm-based concurrent estimation (GA-CE) method is proposed to search for the initial parameter set that minimizes the output estimation error. This optimal concurrent estimation method converges to the optimum or near-optimum solution without any trial-and-error steps for initial values. Validations on the Silverbox and Bouc-Wen hysteresis benchmarks show that the GA-CE method is able to find excellent solutions yielding models with superior predictive performance.
