• Nonlinear Adaptive PID Control for Nonlinear Systems AI翻译

  摘要：This article introduces a nonlinear adaptive proportional-integral-derivative (PID) tracking control methodology suitable for a class of multi-in-multi-out nonlinear systems. By incorporating three nonlinear modulating (trimming) functions to recalibrate the generalized tracking error, a nonlinear PID control framework is constructed that possesses several notable features. First, the user-assignable parameters in the modulating functions allow the resultant control strategy to analytically br...
• Robust Observer-Based Control Design for Stochastic Discrete-Time Quasi-Linear Systems via LMIs AI翻译

  摘要：This work is dedicated to a less conservative observer-based controller design method using linear matrix inequality (LMI) for discrete-time quasi-linear systems with polynomial parameter dependencies subject to stochastic noise. While robust closed loop stability of the deterministic part of the closed loop is guaranteed by a Lyapunov-based approach, the performance is improved by a separate D-R eigenvalue region for the controller and observer. In addition, input, process, and sensor noise i...

  摘要：Sampled-data-based event-triggered (SDET) communication techniques have found extensive applications in the research of synchronization and consensus in directed networks (DNs). However, as the quantity of nodes in a network expands, existing investigations encounter difficulties in obtaining solutions within finite computation times due to computational complexity. For coping with this scenario, a novel event-triggered pinning quasi-synchronization approach is explored in this research for a ...
• Stealthy Attacks on Sampled-Data Control and Encryption-Based Countermeasures AI翻译

  摘要：This article investigates stealthy attacks on sampled-data control systems, where a continuous process is sampled periodically, and the resultant discrete output and control signals are transmitted through dual channels in wireless communication networks. Acknowledging the vulnerability of these transmitted data to cyber threats, we analyze two types of stealthy attacks that compromise either one or both channels. We explicitly present the necessary and sufficient conditions for the existence ...
• On Lie-Bracket Averaging for Hybrid Dynamical Systems With Applications to Model-Free Control and Optimization AI翻译
  作者：Abdelgalil, Mahmoud; Poveda, Jorge I.
  作者单位：University of California System; University of California San Diego
  摘要：The stability of dynamical systems with oscillatory behaviors and well-defined average vector fields has traditionally been studied using averaging theory. These tools have also been applied to hybrid dynamical systems, which combine continuous and discrete dynamics. However, most averaging results for hybrid systems are limited to first-order methods, hindering their use in systems and algorithms that require high-order averaging techniques, such as hybrid Lie-bracket-based extremum-seeking a...
• System Class Extensions of the Modulating Function-Based State Reconstruction for the Advection-Diffusion-Reaction Equation AI翻译
  作者：Friedrich, Folke; Fokken, Nils; Noack, Matti; Reger, Johann
  作者单位：Technische Universitat Ilmenau
  摘要：In this article, the state estimation of distributed parameter systems using the modulating function method is extended to systems of two or higher spatial dimensions with spatially varying coefficients and general boundary conditions. At the center of the state observer approach lies the construction and solvability analysis of systematically obtained kernel equations determining the modulating functions. In addition, a method for the state estimation of a class of parabolic systems with time...
• Generalized Simultaneous Perturbation-Based Gradient Search With Reduced Estimator Bias AI翻译

  摘要：We present a family of generalized simultaneous perturbation-based gradient search (GSPGS) estimators that use noisy function measurements. The number of function measurements required by each estimator is guided by the desired level of accuracy. We first present in detail unbalanced generalized simultaneous perturbation stochastic approximation estimators and later present the balanced versions of these. We extend this idea further and present the generalized smoothed functional and generaliz...
• Finite-Dimensional Backstepping Controller Design AI翻译
  作者：Kalantarov, Varga K.; Ozsari, Turker; Yilmaz, Kemal Cem

  摘要：In this article, we introduce a finite-dimensional version of backstepping controller design for stabilizing solutions of partial differential equations (PDEs) from boundary. Our controller uses only a finite number of Fourier modes of the state of solution, as opposed to the classical backstepping controller which uses all (infinitely many) modes. We apply our method to the reaction-diffusion equation, which serves only as a canonical example but the method is applicable also to other PDEs wh...
• Resilient Distributed Optimization for Multiagent Cyberphysical Systems AI翻译
  作者：Yemini, Michal; Nedic, Angelia; Goldsmith, Andrea J.; Gil, Stephanie
  作者单位：Bar Ilan University; Arizona State University; Arizona State University-Tempe; Princeton University; Harvard University
  摘要：This work focuses on the problem of distributed optimization in multiagent cyberphysical systems, where a legitimate agent's iterates are influenced both by the values it receives from potentially malicious neighboring agents and by its own self-serving target function. We develop a new algorithmic and analytical framework to achieve resilience for the class of problems where stochastic values of trust between agents exist and can be exploited. In this case, we show that convergence to the tru...

  摘要：In this note, we present the synthesis of secure-by-construction controllers that address safety and security properties simultaneously in cyber-physical systems. Our focus is on studying a specific security property called opacity, which characterizes the system's ability to maintain plausible deniability of its secret behavior in the presence of an intruder. These controllers are synthesized based on a concept of so-called (augmented) control barrier functions (CBFs). We propose conditions t...
