TL;DR: The aim of this paper is to review the state-of-the art of methods and techniques for fault diagnosis of Discrete Event Systems based on models that include faulty behaviour.

TL;DR: The methods which have been investigated and the controllers used, first for balancing and movement of two-wheeled robots on flat terrain, then for two-wheeleled robots in other situations, where terrain may not be flat, where there may be secondary objectives and where the robots may have additional actuators.

TL;DR: The paper examines developments from four distinct perspectives: conceptual developments, theoretical issues, practical deployment and business opportunities, and identifies four key obstacles to be overcome in order to successfully deploy product intelligence in an industrial application.

TL;DR: This paper also discusses system identification techniques and some important implementation issues, like the time-delay in the system, estimation of velocity and position from acceleration signals, and optimal placement of the sensors and control devices.

TL;DR: This invited contribution aims to combine some historical facts with elements of a conceptual view on concurrent DEDS, giving pointers about the development of the field.

TL;DR: The review covers the sensorless SMC schemes by integrating controller and observer design to guarantee convergence of the estimates to the real states and covers the chattering problems, encountered often in SMC area dealt by using an asymptotic observer.

TL;DR: Lyapunov-based conditions for stability and recurrence are presented for a class of stochastic hybrid systems where solutions are not necessarily unique, either due to nontrivial overlap of the flow and jump sets, a set-valued jump map, or a set ofvalued flow map.

TL;DR: This paper reviews recent work on models and methods for studying the mechanisms of collective migration and collective decision-making in high-performing animal groups and proves systematically how behavior depends on parameters that model the system and the environment.

TL;DR: An extension of recent results about the design of stable interval observers for linear systems with additive time-varying zonotopic input bounds allows the explicit computation of adaptive thresholds ensuring a guaranteed robustness with respect to structured and bounded disturbances which can be not only additive but also multiplicative.

TL;DR: Some new results on distributed fault diagnosis of continuous-time nonlinear systems with partial state measurements are proposed and theoretical results dealing with detectability and isolability sufficient conditions are presented.

TL;DR: Robustness and performance of the proposed fault detection scheme are tested using a high fidelity benchmark and intensive Monte Carlo simulations for several flight scenarios as specified within ADDSAFE project.

TL;DR: A novel robust sensor fault tolerant control strategy for systems with linear parameter varying (LPV) uncertainty model description is proposed, which is guaranteed to preserve boundedness of the closed-loop system trajectories under a wide range of sensor fault scenarios.

TL;DR: This paper focuses on retroactivity and review techniques, based on nonlinear control and dynamical systems theory, that are developed to quantify the extent of modularity of biomolecular systems and to establish modular analysis and design techniques.

TL;DR: An overview of how three branches of science, namely Systems Biology, Synthetic Biology and Control Theory might be interlaced to help solve relevant problems in medicine and biotechnology is provided.

TL;DR: This paper provides an extension and a generalization of the fault detectability and the reconstruction-based fault isolabilty concepts in order to be valid for the use of any detection index having a quadratic-form.

TL;DR: This work makes use of a passivity-based approach (PBA) and tools from Lyapunov theory to design a nonlinear controller for the asymptotic stabilization of a class of nonisothermal Continuous Stirred Tank Reactors around any desired stationary point.

TL;DR: This paper resumes and better formalizes the two complementary definitions of set-membership identifiability and μ-set- membership identIFiability and presents a method applicable to nonlinear systems for checking them and proposes a method for fault detection and identification.

TL;DR: Initial work including model development and calibration together with preliminary control system design is reported, aimed at the design of a closed-loop control strategy incorporating feedback from the available measurements.

TL;DR: This work proposes an optimization-based design method for which two properties will be guaranteed simultaneously despite parametric uncertainty, namely, closed-loop stability with bounded inputs and feasibility of the transient in the presence of state constraints.

TL;DR: It is found that the best control strategy to reduce the HBV infection is the combination of treatment in blocking new infection and treatment in inhibiting viral production.

TL;DR: It is shown that addictive substances are more likely to have state-dependent solution trajectories, and that in turn can create path dependence at the macro-policy level; in particular, legalization may be an irreversible experiment.

TL;DR: The aim of this paper is to assess the reliability of a fault detection and isolation scheme (FDI) and the impact of sensor’s failure probability on such scheme and a simple maintenance strategy to maintain the level of the property reliability is proposed.

TL;DR: A new method for fault isolation in a class of continuous-time stochastic dynamical systems is proposed, characterized by deriving for the unidimensional case, a sufficient isolability condition as well as an upperbound of the probability of missed isolation.
