• Velocity-Free Event-Triggered Control for Multiple Euler-Lagrange Systems With Communication Time Delays AI翻译

  摘要：This article considers the consensus problem of multiple Euler-Lagrange systems subject to unavailable velocity information and limited communication resources. First, a new event-triggered communication scheme, based on designing a virtual system for each agent, is proposed to achieve the coordination task without velocity information. The event-triggering conditions only rely on the states of virtual systems and allow agents to transmit virtual states only at some discrete time instants. Und...
• A Distributed Indirect Adaptive Approach to Cooperative Tracking in Networks of Uncertain Single-Input Single-Output Systems AI翻译

  摘要：Current approaches to the cooperative control of network systems are based on a priori knowledge about the (follower) system dynamics: either the dynamics are known, or assumed to be minimum phase, or initial stabilizing controllers are available for each system. The purpose of this article is to show that for single-input single-output systems (SISO) the above assumptions can be relaxed. We propose an indirect adaptive methodology that does not require the knowledge of the parameters of the s...
• Optimal Transport Between Gaussian Stationary Processes AI翻译

  摘要：We consider the optimal transport problem between multivariate Gaussian stationary stochastic processes. The transportation effort is the variance of the filtered discrepancy process. The main contribution of this article is to show that the corresponding solution leads to a weighted Hellinger distance between multivariate power spectral densities. Then, we propose a spectral estimation approach in the case of indirect measurements, which is based on this distance.
• Observation for Markov Jump Piecewise-Affine Systems With Admissible Region-Switching Paths AI翻译

  摘要：The article investigates the problem of state observation for discrete-time Markov jump piecewise-affine (PWA) systems, which cover both Markov jump systems and traditional PWA systems as two special classes. A new method for determining the admissible region-switching paths between adjacent time instants is proposed for both the plant state and the estimator state, so that both the computation cost and the conservatism of the theoretical results are reduced. To analyze the mean-square stabili...
• Real-Time Scheduling Based on Nonblocking Supervisory Control of State-Tree Structures AI翻译

  摘要：This article presents a novel framework for the modeling and scheduling of real-time systems (RTS) processing both sporadic and (multiperiod) periodic tasks, based on nonblocking supervisory control of state-tree structures. Instead of assigning static priorities, a real-time scheduling mechanism, namely priority-free conditionally preemptive scheduling, is used to describe the preemption relation among the tasks processed in an RTS. As a dynamic priority scheduling mechanism, partially preemp...
• Fast Self-Triggered MPC for Constrained Linear Systems With Additive Disturbances AI翻译
  作者：Dai, Li; Cannon, Mark; Yang, Fuwen; Yan, Shuhao

  摘要：This article proposes a robust self-triggered model predictive control (MPC) algorithm for a class of constrained linear systems subject to bounded additive disturbances, in which the intersampling time is determined by a fast convergence self-triggered mechanism. The main idea of the self-triggered mechanism is to select a sampling interval so that a rapid decrease in the predicted costs associated with optimal predicted control inputs is guaranteed. This allows for a reduction in the require...
• Saturated Lipschitz Continuous Sliding Mode Controller for Perturbed Systems With Uncertain Control Coefficient AI翻译
  作者：Martinez-Fuentes, Carlos Arturo; Seeber, Richard; Fridman, Leonid; Moreno, Jaime A.

  摘要：In this article, a Lipschitz continuous sliding mode controller (LCSMC) is proposed to stabilize an integrator chain with a saturated control input, Lipschitz continuous perturbations, and an unknown control coefficient. The proposed controller ensures global finite-time convergence to the sliding surface by means of a control signal that is Lipschitz continuous (i.e., has finite gain) and is bounded by a given actuator limit. Stability conditions for the controller's tuning parameters are der...
• Optimal Linear Encryption Against Stealthy Attacks on Remote State Estimation AI翻译
  作者：Shang, Jun; Chen, Maoyin; Chen, Tongwen
  作者单位：University of Alberta; Tsinghua University
  摘要：Defending against malicious attacks has become increasingly important in various cyber-physical systems. This article presents an encryption-based countermeasure against stealthy attacks on remote state estimation. Smart sensors transmit data to a remote estimator through a wireless communication network, in which data packets can be intercepted and compromised by attackers. The remote end is equipped with a false data detector that monitors the system. To avoid being detected, the attack shou...
• Control of Nonlinear Uncertain Systems by Extended PID AI翻译

  摘要：Since the classical proportional-integral-derivative (PID) controller is the most widely and successfully used ones in industrial processes, it is of vital importance to investigate theoretically the rationale of this ubiquitous controller in dealing with nonlinearity and uncertainty. Recently, we have investigated the capability of the classical PID control for second-order nonlinear uncertain systems, and provided some analytic design methods for the choices of PID parameters, where the syst...
• A Hybrid Thermodynamic Control Protocol for Semistability and Consensus of Network Systems With Intermittent Information AI翻译

  摘要：Network systems involve distributed decision making for coordination of networks of dynamic agents and address a broad area of applications in science and engineering. In this article, we develop a thermodynamically based framework for addressing consensus problems using a hybrid control protocol architecture with a dynamic communication topology wherein communication events are triggered via state-dependent resettings consistent with thermodynamic principles. The proposed hybrid controller ar...
