TL;DR: Numerical experiments on benchmark problem instances indicate that HIFOO could be an efficient and reliable computer-aided control system design (CACSD) tool, with a potential for realistic industrial applications.

TL;DR: Results show that the public transport users of this study can rapidly be divided in four major behavioural groups, whatever type of ticket they use, which demonstrates that a combination of planning knowledge and data mining tool allows producing travel behaviours indicators, mainly regarding regularity and daily patterns.

TL;DR: In this article, the stability of time delay systems is investigated considering the delay-dependent case and the system without delays is assumed stable and conservative conditions are derived for finding the maximal delay that preserves stability.

TL;DR: In this article, the authors argue that fractional order control is ubiquitous when the dynamic system is of distributed parameter nature and that the best fractional-order controller outperforms the best integer order controller.

TL;DR: The chattering can be caused by fast dynamics which were neglected in the ideal model, and these `unmodeled' dynamics with small time constants are usually disregarded in models of servomechanisms, sensors and data processors.

TL;DR: In this article, a least absolute shrinkage and selection operator (LASSO) technique is investigated for computing efficient model descriptions of nonlinear systems, which is a natural extension of this constrained minimisation approach to pseudolinear regression problems which produces some model parameters that are exactly zero and yields a parsimonious system description.

TL;DR: In this paper, an improved way of constructing a Lyapunov-Krasovskii functional for a linear time delay system is provided, which is based on the reformulation of the original system and a discretization scheme of the delay.

TL;DR: In this paper, several important issues on the integrated design of Fault Detection and Diagnosis (FDD) schemes together with Reconfigurable Control (RC) for Active Fault-Tolerant Control Systems (AFTCS) are addressed and discussed.

TL;DR: In this paper, the relationship between Lyapunov stability, Poincare stability, and Zhukovsky stability is considered and stability and instability criteria by the first approximation are obtained.

TL;DR: The approach is to make unmarked siphons satisfy cs-property when the elementary ones are properly supervised, the advantage of the novel method is that a much smaller number of supervisory monitors and arcs are added and unnecessary iterative processes are avoided.

TL;DR: A collection of interactive learning modules for PID control based on the graphical spread sheet metaphor designed to speed-up learning and to enhance understanding of the behavior of loops with PID controllers is described.

TL;DR: In this paper, the Laplace transform is applied to obtain the general explicit solutions for the equations being studied in terms of Mittag-Leffler functions and generalized Wright functions conditions are given for obtaining linearly independent solutions which form a fundamental system of solutions.

TL;DR: In this paper, the focus is on direct optimizing control by optimizing an economic cost criterion online on a finite horizon where the usual control specifications in terms of e.g. product purities enter as constraints and not as setpoints.

TL;DR: The DARPA Grand Challenge was the most significant event in the field of robotics in more than a decade as discussed by the authors, and a mobile ground robot had to traverse 131 miles of punishing desert terrain in less than ten hours.

TL;DR: In this article, a non-integer order linear differential equation is used to determine the damping ratio of the oscillatory mode of the solution of a dyke with fractal dimension.

TL;DR: The tutorial starts with some general aspects on time and frequency-domain representations, time-domain simulation, and stability of fractional models, and an overview on system identification methods using fractional Models is presented.

TL;DR: In this paper, an adaptive Luenberger-type observer based on a set of two coupled one dimensional first order nonlinear hyperbolic partial dierential equations governing the flow dynamics is designed.

TL;DR: In this paper, a double layer ultracapacitor was identified using impedance spectroscopy and two novel methods were proposed based on the fractional calculus with a few parameters.

TL;DR: In this paper, the robust stability of time delay systems by means of quadratic separation theory is considered. But the robustness is not shown to be equivalent to other LMI-based results from the literature.

TL;DR: Several tuning rules for fractional PID controllers, similar to the first and the second sets of tuning rules proposed by Ziegler and Nichols for integer PIDs, are presented.

TL;DR: Two methods are proposed to solve the anaesthesiology nurse scheduling problem (ANSP of a French public hospital, where the anaesthesia nurses constitute one of the most shared resources) based on integer programming and constraint programming.

TL;DR: In this paper, a new tuning method for PI α controller design is proposed for a class of unknown, stable, and minimum phase plants, where the phase derivative w.r.t. the frequency is zero, at a given gain crossover frequency.

TL;DR: Observers are synthesized for switched linear systems, resulting in switched observers including state jumps, and it will be shown that the bound of the estimation error can be reduced significantly.

TL;DR: In this paper, an optimal skyhook control based on industrial specification, coupled with a reduced order observer when only one sensor is to be used, is derived for real-time embedded applications.

TL;DR: The paper illustrates the complex nature of EU ATFM solutions, the benefits that can be obtained by assigning some airborne holding delays in addition to ground delays, and the issues of equity that arise in the EU AT FM context as a result of the interactions among traffic flows.

TL;DR: In this article, a guaranteed solution based on Muller's theorems and interval analysis is proposed for bounded-error state estimation for models described by a continuous-time state equation from discrete-time measurements.

TL;DR: In this article, a fault tolerant control strategy based on the linear quadratic problem is proposed for aircraft longitudinal dynamics control, which progressively accommodates the feedback control law according to the iteration solutions of the Newton-Raphson algorithm.

TL;DR: Using the so-called simulation functions, a computationally effective characterization of approximate simulation relations is developed which can be used for hybrid systems approximation.

TL;DR: In this article, an approximate analytical method for evaluating the performance of production systems in which SPC techniques are implemented is proposed, where machines behaviour is monitored by measuring quality characteristics of produced parts using off-line inspection devices and sampling inspections.
