TL;DR: The present paper aims at providing a generic set of integral inequalities which are asymptotically non conservative and then to design functionals driven by these inequalities, which form a hierarchy of LMI which is competitive with the most efficient existing methods.

TL;DR: Both theoretical and numerical results show that the optimal load sharing can be achieved within both generation and delivering constraints in a distributed way.

TL;DR: A new method is proposed for robust static output feedback H ∞ controller design that is applicable for general uncertain systems, without the need to impose any constraints on system matrices.

TL;DR: It is shown that, with the proposed observer-based consensus algorithm, the leader–follower consensus problem can be solved and a simulation example is presented to demonstrate the effectiveness of the proposed algorithm.

TL;DR: By dividing the tracking error dynamic system into a cascade of two subsystems, the torques in surge and yaw axes are designed separately using the backstepping technique, which enables them to be de-coupled from the second subsystem after a finite time.

TL;DR: This paper rewrite the original networked switched systems by sampled asynchronous switched systems with time-varying delays by giving the co-design conditions on both the switching signal and the controllers which depend on the sampling time, the upper bound of network-induced delays, and the asynchronous occurring frequency.

TL;DR: A novel position-based tracking protocol is designed and analyzed for solving the distributed finite-time tracking problem when both velocity and acceleration measurements are not available for the followers.

TL;DR: Under the assumption that the network has sufficient connectivity in terms of robustness, this work develops a resilient algorithm where each agent ignores the neighbors which have large and small position values to avoid being influenced by malicious agents.

TL;DR: A succinct algebraic expression of dynamic programming algorithm is derived to solve the optimal control problem for the stochastic logical dynamical systems with finite states.

TL;DR: It is proved that the formation problem concerned is solved if and only if the linear systems are controllable and an optimal formation control law is developed for multi-agent systems based on some invertible conditions.

TL;DR: In this paper, the problem of non-fragile passive control for Markovian jump systems with aperiodic sampling is investigated and a mode-independent state feedback sampled-data controller is designed such that for all admissible uncertainties the closed-loop system is robustly stochastically passive.

TL;DR: The sums of squares conditions are proven to approximate arbitrarily well the conditions of Geromel and Colaneri (2006) and be invariant with respect to time-scaling, emphasizing that the complexity of the approach does not depend on the size of the dwell-time.

TL;DR: This paper proposes a resource-aware self-triggered MPC strategy for discrete-time nonlinear systems subject to state and input constraints that has three important features: significant reductions in resource utilization can be realized without modifying the cost function by input regularization or explicitly penalizing resource usage.

TL;DR: The proposed approach is shown to be applicable to position estimation of a class of electromechanical systems and to two assumptions related to solvability of a partial differential equation and the ability to estimate the unknown parameters.

TL;DR: A nonlinear ESO is designed for a kind of lower triangular nonlinear systems with large uncertainty, which may come from unmodeled system dynamics and external disturbance.

TL;DR: A distributed periodic event-triggered strategy and a detailed DRHC algorithm are designed and it is shown that the closed-loop system is input-to-state stable if the energy bound of the disturbances, the triggering condition and the cooperation matrices fulfill the proposed conditions.

TL;DR: A scheme for an integrated design of observer-based FD systems for affine nonlinear systems is proposed, considerably inspired by the study on input–output stability and stabilization of non linear systems.

TL;DR: This paper addresses the problem of H − / H ∞ fault detection for two-dimensional systems with disturbances in Roesser model by the generalized Kalman–Yakubovich–Popov lemma and some useful lemmas and sufficient design conditions are obtained.

TL;DR: This paper has three major innovations compared with reported studies, namely, the stochastic sequence model of packet loss, the novel control direction regulation method, and the almost sure convergence property of the proposed algorithm.

TL;DR: It is proved that exponential stability of the closed-loop system, under the proposed PI control law, when the parameters of the plant and the controller satisfy certain conditions, is proved by constructing a novel “non-diagonal” Lyapunov functional.

TL;DR: The anti-disturbance controllers are designed respectively with both the polytopic and dead-zone representations of the saturation function, which ensure that the resulting closed-loop systems are asymptotically stable with an estimation of the domain of attraction described by the level set of the Lyapunov function.

TL;DR: The aim is to accurately estimate online the state vector of the ODE subsystem and the distributed state of the PDE element and to ensure the observer exponential convergence.

TL;DR: Barbalat-like lemmas for fractional order integrals are presented, which can be used to conclude about the convergence of a function to zero, based on some conditions upon its fractional integral.

TL;DR: It is shown analytically that the proposed robust adaptive tracking controller for systems with arbitrary relative degree and known high-frequency gain is robust against bounded disturbances and using projection technique to prevent parameter drift.

TL;DR: Stability criteria characterizing the asymptotic stability of a class of LPV systems with piecewise constant parameters under constant and minimum dwell-time are derived and are extended to address the stabilization problem using a particular class of time-dependent gain-scheduled state-feedback controllers.

TL;DR: It is shown that, providing the switching signals neither switch too frequently nor activate non-ISS subsystems for too long, a small-gain theorem can be used to conclude global asymptotic stability (GAS) of the interconnected system.

TL;DR: Using this procedure, the closed-loop system can be guaranteed to be robustly stable against any strict negative imaginary uncertainty, such as in the case of unmodeled spill-over dynamics in a lightly damped flexible structure.

TL;DR: A new reduced mode model for stability analysis of large-scale distributed networked control systems with random communication delays is proposed and a new method that estimates bounds for uncertain Markov transition probability matrix is provided to guarantee the system stability.

TL;DR: The paper considers the problem of stabilization of systems possessing a multiple zero eigenvalue at the origin and proposes a controller that uses multiple delayed measurements instead of derivative terms to increase the performances of the closed loop in presence of system uncertainties and/or noisy measurements.

TL;DR: A condition under which infinite horizon discounted optimal control problems can be used in order to obtain stabilizing controls for nonlinear systems is provided.
