This paper considers the event-triggered (ET) platoon control of connected vehicles in the presence of actuator failures and DoS attacks. First, a historical attack-intensity-based ET mechanism is proposed to optimize communication resources. Compared with the existing event trigger mechanism, this mechanism utilizes not only the state error information but also historical attack intensity data to dynamically adjust the trigger threshold, which further conserves communication resources and enhances design flexibility in the case of DoS attacks. Next, a security platoon control scheme is designed to resist actuator faults and DoS attacks, and a delay switched system model is introduced to describe the vehicle platoon tracking error system. Then, a novel Lyapunov functional is developed and combined with switching techniques to establish sufficient conditions for the exponential stability of the tracking error system. Additionally, a co-design method of controller gain and event trigger parameters is proposed. Finally, simulation examples validate the superiority of the proposed historical attack-intensity-based ET platooning control scheme. © 1967-2012 IEEE.

The remarkable success of foundation models has sparked growing interest in their application to single-cell biology. Models like Geneformer and scGPT promise to serve as versatile tools in this specialized field. However, representing a cell as a sequence of genes remains an open question since the order of genes is interchangeable. Injecting the gene network graph offers gene relative positions and compact data representation but poses a dilemma: limited receptive fields without in-layer message passing or parameter explosion with message passing in each layer. To pave the way forward, we propose GenoHoption, a new computational framework for single-cell sequencing data that effortlessly combines the strengths of these foundation models with explicit relationships in gene networks. We also introduce a constraint that lightens the model by focusing on learning the predefined graph structure while ensuring further hops are deducted to expand the receptive field. Empirical studies show that our model improves by an average of 1.27% on cell-type annotation and 3.86% on perturbation prediction. Furthermore, our method significantly decreases computational overhead. Overall, GenoHoption can function as an efficient and expressive bridge, connecting existing single-cell foundation models to gene network graphs.1 © 2024 IEEE.

The present paper aims to design an integrated state/fault estimation and fault tolerant control issues for switched systems affected by actuator fault and external disturbances. A switched adaptive state/fault estimation observer is proposed to simultaneously estimate the system state and actuator fault. Based on this observer, we develop a fault tolerant control law not only to stabilize the closed-loop system, but also to compensate the faults effects. Then, by using the switched Lyapunov function and Average Dwell Time (ADT) concept, some sufficient conditions are derived and applied to build the switched adaptive observer-based state feedback controller. The observer and controller gain matrices are also obtained by solving an optimization problem with Linear Matrix Inequality (LMI) constraints. Finally, simulation results of a switched electrical system are presented to illustrate the effectiveness of the proposed design methods. © 2023 IEEE.

This paper considers the problem of designing a robust descriptor observer for simultaneous state and sensor faults estimation of continuous-time switched linear systems in the presence of unknown external disturbances. An augmented singular switched system is constructed from the original switched systems by considering the sensor faults term as a part of a new extended state vector. Stability conditions are established and formulated into H∞ performances by minimizing the effect of external disturbance from the residual and a Lyapunov stability theory is utilized for switched system stability combined with the Average Dwell Time (ADT) concept. The observer parameter matrices are also determined by solving a convex optimization problem under Linear Matrix Inequalities (LMI) constraints. Finally, a numerical example and a Highly MAneuverable Technology (HiMAT) vehicle are investigated to prove the efficacy of the obtained results. © 2023 IEEE.

This paper proposes an integrated design of fault tolerant control (FTC) for continuous-time switched systems in the presence of sensor faults and external disturbances. A switched descriptor observer is proposed to estimate the sensor faults and system states simultaneously, and using the estimates, a state feedback fault-tolerant controller is constructed to en-sure the robust stability of the closed-loop system. The observer and controller gain are determined through H∞optimization using a one-step Linear Matrix Inequality (LMI) formula. This is achieved by utilizing multiple Lyapunov functions and the concept of Average Dwell Time (ADT) switching signal. Sufficient conditions, characterized by reduced conservatism, are then derived and expressed in LMI form. Finally, a simulation analysis of a two-tank liquid level control system is presented to illustrate the effectiveness of the developed integrated FTC strategy. © 2023 IEEE.

In this paper, a novel adaptive dynamic programming (ADP) algorithm, named output-feedback hybrid iteration (HI),is proposed to address the adaptive optimal control problem of discrete-time linear systems. The proposed output-feedback HI strategy learns the optimal control policy through two phases. First, a novel data-driven value-iteration (VI) scheme is employed to learn an admissible output-feedback control policy using the input/output data without relying on the knowledge of system matrices. Then, with the obtained admissible control policy, the optimal output feedback-control policy is approximated with an accelerated convergence rate through output-feedback policy iteration (PI). Online input/output data are utilized to reconstruct the full state of the system and integrated into the new output-feedback HI algorithm. Simulation results are presented and demonstrate the efficacy and practicality of the proposed output-feedback HI approach in comparison with traditional PI and VI techniques. © 2024 IEEE.

In this paper, observer-based adaptive neural pre-defined performance control is studied for non-affine multi-agent systems with input delay. Compared with existing results, a variable parameters predefined performance control method for multi-agent system is proposed. In addition, Pade approximation and mean value theorem are used to solve the obstacles of input delay and non-affine term. Different from the dynamic surface control(DSC) method, the command filter (CF) method can also solve the problem of computational explosion in the backstepping design, and the filter error generated is well eliminated. By utilizing adaptive backstepping technique and Lyapunov stability theorem, it is proved that all signals in multi-agent systems are cooperative semi-global uniform and ultimately bounded (CSUUB). The observer estimation errors and the tracking errors within a predefined range converge on a small neighborhood. Simulation results are provided to demonstrate the effectiveness of the proposed method. © 2023 IEEE.
