TL;DR: This paper presents a tutorial overview in three main parts: the general setup and the basic IQC theorem, an extensive survey on the formulation and parametrization of multipliers based on LMI constraints, and a detailed illustration of how the tools can be applied.

TL;DR: This review article describes the design of static controllers that achieve an optimal tradeoff between closed-loop performance and controller structure by incorporating regularization functions into the optimal control problem and optimizing the controller over the identified structure.

TL;DR: This tutorial paper aims to provide a clear and comprehensive introduction to the topic of absolute stability from a user viewpoint, reviewing the stability theory, the properties of the multipliers (including their phase properties, phase-equivalence results and the issues associated with causality), and convex searches.

TL;DR: A method to simplify the partial differential equations (PDEs) associated to the potential energy for interconnection and damping assignment passivity based control of a class of underactuated mechanical systems (UMSs) is developed, and some realistic simulations are presented which validate the proposed control design method and prove that global stabilization of these systems can be achieved.

TL;DR: A systematic overview of the body of knowledge and algorithmic techniques for verification and strategy synthesis for stochastic games with respect to a broad class of quantitative properties expressible in temporal logic is offered.

TL;DR: A simple and novel method is proposed to provide the stabilization feedback gain K, such that the controlled system tracks the reference signal generated by an exosystem with its spectrum on the imaginary axis.

TL;DR: If an independent leader vehicle is added to the formation and every follower has access to this leader position, the cyclic formation with a constant spacing policy can be made stable and string stable by appropriately selecting a design parameter.

TL;DR: A novel adaptive actuator failure compensation controller is developed based on the backstepping design method to compensate the unknown time varying actuator failures as well as uncertainties from unknown nonlinearities and time varying delays.

TL;DR: By virtue of Girsanov׳s theorem and the standard spike variational technique, the maximum principle for the partially observed control problems is established and the sufficient condition is obtained for the special case by using some concavity conditions.

TL;DR: It is shown that, under some sufficient conditions on a given couple of initial and desirable states, the considered system can be steered in L 2 ( Ω ) from its initial state into any neighborhood of the given desirable target state by means of a static control.

TL;DR: This work obtains a scalable formation of the UAVs around the target which uses only bearing angle information of the target and the neighbours and analysed the local stability of equilibrium formations.

TL;DR: A new robust regulation control scheme is developed for time-varying strict feedback nonlinear systems with unknown control directions using the nonlinear PI method within an integrator backstepping framework.

TL;DR: This article presents a class of switching signals under which the resulting switched system is ISS, and allows non-ISS systems in the family and the analysis involves graph-theoretic arguments.

TL;DR: The state feedback laws proposed in this work guarantee almost global asymptotic stability of the desired closed-loop equilibrium.

TL;DR: Experimental results confirm the efficacy of the proposed identification procedures, and show that high levels of accuracy can be achieved in a short identification time using test procedures that are suitable for future transference to the clinical domain.

TL;DR: A novel analysis technique based on classical notions of persistence of excitation and uniform complete observability for consensus laws under time-varying graphs provides explicit bounds on rate of convergence to consensus for single integrator dynamics.

TL;DR: The proposed derivative free estimator has the capability to deal with highly nonlinear systems like the CKF, and like the H ∞ filter it can estimate states with stochastic or deterministic noises, and it can be easily extended to handle measurements from multiple sensors.

TL;DR: An approximation method based on the moments of a random variable is used that results in a much lower computation time and a much higher computational complexity than the existing computational methods while still guaranteeing a performance that is comparable to the performance of those methods.

TL;DR: The overall scheme is shown to reduce, in some special cases, to a nonlinear version of a PI type of control action.

TL;DR: A novel control method is proposed to regulate the outputs of the five-level diode-clamped converter topology, based on several steps carried out during the controller design stage that lead to define a discrete-time controller with sampling frequency corresponding to the triple of the ac-source frequency.

TL;DR: N nondegenerate necessary conditions of optimality are derived and discussed for the so-called “minimax” optimal control problems with state constraints, where the data depends on an unknown parameter that takes values in a given compact set called “uncertainty set”.

TL;DR: This work adopts for the first time the active disturbance rejection control approach to stabilization of multi-dimensional partial differential equations under corrupted output feedback and shows that with a time varying gain properly designed, the observer driven by the disturbance estimator is convergent; and that all subsystems in the closed-loop are asymptotically stable.

TL;DR: An overview of recent developments in the Input-to-State Stability framework is presented, dealing in particular with the extension of the classical concept to systems with multiple invariant sets and possibly evolving on Riemannian manifolds.

TL;DR: This work investigates the advantages and limitations of the feedforward class using three-node circuits representative of these architectures, and suggests two ways in which this tradeoff can be alleviated: by introducing a nonlinearity in the production of a specific node in the network, or by adding a feedback loop to the input.

TL;DR: Under the channel encoder without access to control inputs, a coding scheme based on spherical polar coordinates is proposed for this problem, which simplifies the design of the coding scheme.

TL;DR: The use of this approach drastically simplifies the design of the central controller and provides even better results than (Castellanos Silva et al., 2013 [4] ) with the advantage to use a single central controller independent of the number of narrow band disturbances.

TL;DR: It is proved that the resulting closed-loop system is exponentially stable and a brand-new output feedback law is proposed by a completely new transformation.
