TL;DR: In this paper, the existence of non-negative storage functions was shown to be equivalent to the equivalence of dissipativity with existence of a nonnegative storage with constant-coefficient linear PDE.

TL;DR: In this paper, the identification of hybrid models with a hybrid structure is discussed, and the main features of the selected procedures are presented, and possible interactions to still enhance their effectiveness are suggested.

TL;DR: In this paper, the authors provide a tutorial overview of fault-tolerant control over the network for network control systems (NCS) that are likely to lead to good fault tolerant control properties, subject to network faults.

TL;DR: This paper presents an introduction to Monte Carlo and Las Vegas randomized algorithms for systems and control, specific applications of these algorithms include stability analysis, Lyapunov functions, and distributed consensus problems.

TL;DR: In this article, the authors survey recent work on parametric linear programming from the point of view of the control engineer and identify three types of algorithms, two arising from standard convex hull paradigms and one from a geometric intuition, and classify all currently proposed methods under these headings.

TL;DR: A new control law based on an extended kinematic model (updated on-line via an adaptive method) is proposed and discussed, and a model predictive control approach is added to limit such transient phases in cases where a curved path is followed.

TL;DR: In this paper, the authors propose the use of a component approach to address embedded control problems and outline a general coponent-based framework to embedded control aid show how it can be instantiated inspecific problems that arise in the control over/of sensor networks.

TL;DR: This work proposes a Sliding Mode approach to the design of an active braking controller whose controlled variable is a convex combination of wheel deceleration and wheel slip.

TL;DR: In this work a new methodology which allows preserving continuous-time passivity is presented, based on choosing a proper output, which preserves the passivity structure, while keeping the continuous- time energy function.

TL;DR: I entered the field of control as a Ph.D. student at MIT in September 1965, and during my years at MIT, I had the good fortune to become personally acquainted and develop close professional relationships with many of the pioneers of the subject, among others.

TL;DR: Algorithms proposed in this paper estimate the friction torque during engine start and idle via a deviation from the reference model using Newton’s second law for rotational dynamics.

TL;DR: A new method is proposed to estimate the upper bound of the derivative of Lyapunov functional without ignoring some useful terms and improved delay-dependent stability criteria are established by taking into account the range for the time-delay.

TL;DR: An overview of the important developments in the automotive engine control systems in the last few decades and discusses some of the prospects that new technologies promise can be found in this article, where the authors present a model-based systematic control of the complex systems.

TL;DR: Simulated results show that the proposed controller with the proposed observer provides high-performance dynamic characteristics, and on the other hand that this scheme is robust with respect to plant parameter variations and external load disturbances.

TL;DR: This result is employed for the solution of a generalized version of the finite-horizon linear quadratic (LQ) problem, encompassing the case of fixed end-point.

TL;DR: A model for trust evaluation that uses pairwise iterated graph games between the agents to create a ‘trust reputation’ with evolution coupled to the game dynamics is described, and a new modeling framework for trust metric evaluation as linear iterations over ordered semirings is presented.

TL;DR: Concept and digital control of metrology lines will be outlined and some experimental results from an on-ground breadboard will be discussed, aiming to reveal sub-nanometric displacements in view of dimensional stabilization/monitoring of demanding space telescopes.

TL;DR: In this paper, the authors focus on recent advances in the control of unmanned aerial vehicles on a single platform basis and suggest challenges in UAV control for extreme performance and reliability, both of which are necessary attributes of vehicle autonomy.

TL;DR: An explicit feedback control ensuring the strong stabilization with decay estimate and minimizing an appropriate cost is given and some examples arising from hyperbolic systems are given.

TL;DR: A robustness analysis for PID-controlled robot manipulators under the influence of external disturbances and a wide class of neglected dynamics, which provides establish uniform semiglobal practical asymptotic stability and proposes a tuning procedure of the PID gains to achieve any given precision from any given bounded set of initial conditions.

TL;DR: A nonlinear control law is proposed that aims at reducing the oscillation by shaping the center manifold, and an oscillation preserving condition was defined and enforced on the system to ensure that the results are physically meaningful and practically implementable.

TL;DR: In this article, a method for designing asymptotically stabilising and adaptive control laws for uncertain nonlinear systems is presented, which relies upon the notions of system immersion and manifold invariance and does not require the knowledge of a control Lyapunov function.

TL;DR: The concepts of selfboundedness and self-hiddenness are generalised and investigated within the general context of non-strictly proper systems and solvability conditions are provided.

TL;DR: Experimental results in the application of an estimator-based delaycompensation algorithm to stabilize a networked control system (NCS) with network-induced stochastic time delays, data-packet losses, and out-of-order data-Packet transmissions are provided.

TL;DR: In this article, a systematic approach to the generation of walking primitive (WP) databases for perception-based guidance control of humanoid 3D bipeds is presented, where individual WPs are computed off-line by optimal control techniques such that they can be concatenated into a physically feasible reference trajectory for walking with step length adaptation, direction changing and stepping over or upon obstacles.

TL;DR: Symmetry reduction and control of the Hamiltonian system of a 2D rigid circular cylinder dynamically interacting with a point vortex external to it is presented, an idealized example in an inviscid framework of fully coupled solid–fluid systems interacting in the presence of vorticity.

TL;DR: A glimpse of the early development of automatic control in Sweden covering the period up to the mid 1960s is given, particularly in the pulp and paper industry, power systems, and military projects.

TL;DR: A full-order Kalman filter is designed under a state feedback decoupling constraint and obtained detection filter includes an adaptive noise cancellation strategy based on the reduced output residuals decoupled from faults.

TL;DR: The paper by Barambones and Garrido presents a further proposal of sensorless control schemes for induction motors, based on the use of field oriented control, but by virtue of theuse of a suitably designed speed observer, can be exploited even in sensorless applications.
