Résumé | Liens | BibTeX | Étiquettes: Fractional systems, Initialization, Interval observers, scopus, Stability of fractional linear systems @article{FREJ2019, In this paper an interval observer is synthesized for fractional linear systems with additive noise and disturbances. The contribution of system whole past to future output is taken into account as an initialization function. Provided the initialization function is upper and lower bounded, it is shown in this paper that the fractional interval observer (FIO) allows to bound pseudo-state free responses by an upper and a lower trajectory. In case interval observers cannot be synthesized straightforwardly, so as to obtain a stable and non-negative estimation error, it is shown that a change of coordinates allows to overcome this problem. The proposed methodology allows to bound fractional systems trajectories when the whole past is unknown but can be bounded. Finally, a numerical example is given to show the effectiveness of the proposed methods on the initialization of fractional linear systems. |

The communication network may introduce time delays while exchanging data among sites connected to the network medium (i.e., the data acquisition site and the remote plant site). Two different approaches are presented in this paper. The first one uses a conventional estimator-based predictor when the uncertainties are supposed to be known. In the case of unknown but bounded uncertainties by known bounds, an interval estimation-based predictor evaluating the set of admissible values for the state is investigated. The state prediction techniques are used to compensate the effect of network-induced delays. Simulation results are introduced to illustrate the efficiency of the proposed techniques. © 2019 IEEE. |

The objective is to develop a novel ℋ∞ observer-based controller so that wider ranges of problems can be solved without too much of mathematics overhead. This new method is based on adding delayed measurements to the Luenberger observer and delayed states to the feedback controller which provide nonrestrictive sufficient conditions. The established sufficient stability conditions are in the form of bilinear matrix inequality (BMI) transformed, through a useful approach, to a convex problem (linear matrix inequality-LMI). A comparison with the classical approach (that uses standard forms of the Luenberger observer and the feedback controller) is presented.

Performances and robustness of gpc controller in an anticipative context Ouvrage De Gruyter, 2019, ISBN: 9783110591729; 9783110590241, (cited By 0). Résumé | Liens | BibTeX | Étiquettes: @book{Achnib2019249, Predictive control has become very popular with practitioners of automatic control due to its design simplicity and relatively good performances. Recent efforts have concentrated into improving the robustness of predictive controllers. In this paper, a method for the tuning of generalized predictive controllers (GPC) using desired closed-loop transfer functions for robust design is evaluated in the context of preview systems supposing that future values of the reference signal are available a number of time steps ahead. This information can be used to reduce the error between the reference signal and the measured output by adding an anticipative action to the controller. The robust predictive control method investigated here reveals some surprising limitations when evaluated in an anticipative context (on a preview system), although satisfactory results are obtained in an non-anticipative context. First the performances and robustness of the obtained GPC controller are validated in an non-anticipative context. Then, it is shown that an equivalent feedforward filter appears when anticipation is added, which can have bad effects on the system performances. An academic simulated example is used to validate our conclusions. © 2019 Walter de Gruyter GmbH, Berlin/Boston. All rights reserved. |

An adaptive fractional order with time delay observer is then constructed to estimate the fault by providing an on-line estimation algorithm.

The objective of this chapter is to develop a novel and simple ℋ∞ observer design method so that wider ranges of problems can be solved without too much of mathematics overhead. The main idea consists in using sliding window of delayed measurements in a Luenberger structure observer in order to get nonrestrictive sufficient conditions.

The conditions that guarantee the existence of this observer are presented in the form of linear matrix inequalities (LMIs). To handle the Lipschitz nonlinearities, the Lipschitz condition and the Young′s relation are adequately operated to add more degrees of freedom to the proposed LMI. Necessary and sufficient conditions for the existence of the unbiased reduced-order observer are given. An extension to H∞ performance analysis is considered in order to deal with H∞ asymptotic stability of the estimation error in the presence of disturbances that affect the state of the system.

Occupancy information in each zone is required in the design of the controller which offers inherent comfort according to the occupancy in the zone. The stability of the building system using the proposed control is verified through the Lyapunov approach. It is also proved that the synergetic controller is robust to external disturbances. Then, synergetic theories are used to design a reconfigurable control for damper stuck failures in variable air volume (VAV) to recover the nominal performance.

NCS is a set of entities communicating and exchanging data via a network, which makes its analysis and synthesis complex. To solve this problem, Petri nets and their modeling potential are used for modeling manufacturing plants as discrete event systems. This powerful method of modeling based on Colored Petri nets (CPN) able to provide a very compact way and a well-Adapted and progressive framework for modeling and analysis complex systems in which competition, synchronization, resource sharing and parallelism are present.

Physical assets and products are becoming more and more mobile, shared, autonomous and computerized and far more resources are no more owned but rent by the industrial operators. Industries have entered in the era of communicating objects and rental of physical assets for productive and economic efficiencies. In this evolutionary and reconfigurable context, classical centralized and deterministic control methodologies based on request/response are no more satisfying to tackle the change of communicating asset paradigm. Asset management is getting closer to the relationship management in a social group of individuals from the same organization or coming from external contractors. In this paper, we propose an innovative approach of object interactions and services management in Industrial IoT, which takes benefits from social relationship paradigm and social group behaviours. The paper describes a unified socio mimetic model for industrial communicating object interactions resulting from a synthesis of the major sociological approaches studied from the sociologic and scientific communities research works. The different principles of social interaction are transposed to industrial communicating objects to shape a new concept of Sociable Industrial Communicating Object, and elementary industrial use cases are discussed. © 2019 IEEE. |

In this paper, method is proposed for reducing the inevitable mutual coupling in a two-element Multiple-Input Multiple-Output (MIMO) antenna network that are extremely close to each other. In order to reduce this coupling, a periodic linear network formed by 4 units square ring resonator (SRR) is inserted between the two ultra wide band (UWB) antennas designed, satisfying the required specifications and obtained from an antenna, based on the introduction of certain modifications. In fact, we have studied the performance of a mass-modified patch antenna consisting of FR-4 which is 25 × 30 × 1.6mm3 a type of substrates. The bandwidth ranges from 3 GHz to 18 GHz in which has a bandwidth of about 15GHz. Simulations performances show that the gain in isolation from antennas with metamaterials is superior to 25 dB in the two frequency bands: 3 to 6 GHz and 12 to 13 GHz. This gain is also greater than 10 dB in the rest of the operating frequency band. © 2019 IEEE. |

Elghoul, A.; Tellili, A.; Abdelkrim, M. N. Reconfigurable control of flexible joint robot with actuator fault and uncertainty Article de journal Dans: Journal of Electrical Engineering, vol. 70, no. 2, p. 130-137, 2019, ISSN: 13353632, (cited By 7). Résumé | Liens | BibTeX | Étiquettes: @article{Elghoul2019130, This paper presents the fault tolerant control (FTC) of a flexible joint robot using singular perturbation method in order to compensate for the lost performance due to the occurrence of actuator fault and the uncertainty. This FTC is based on Lyapunov redesign principle. The singular perturbation method is used to reduce the dynamic model of the flexible joint robot in a fast and slow subsystem. The time scale reduction of the flexible joint model is carried out when their joint stiffness is large enough and the singular perturbation parameter is set to zero. The fault-tolerant control structure in this paper is based on two parts. The first term described the composite control for the system without defect and without uncertainty which represents the sum between slow and fast controllers. While the second term of the fault tolerant command describes additive control designed to compensate for the fault effect of the actuator on the uncertain system. The additive approach is based on the Lyapunov theorem, which guarantees asymptotic stability despite the presence of actuator defects and the parametric uncertainty. The theoretical results are applied on a robot manipulator with a single flexible joint. © 2019 Aymen Elghoul et al., published by Sciendo 2019. |

Due to the introduction of a sliding window of delayed measurements, new LMI conditions are proposed. Indeed, the previous measurements allow increasing the number of decision variables in the LMIs, which render it more general and less conservative than those established by using the standard Luenberger structure of the filter. Analytical and numerical comparisons are provided to demonstrate the superiority of the proposed filter with respect to the standard one. Finally, simulation results and real-time implementation have been presented to illustrate the performances of the new filter. © 2004-2012 IEEE. |

Résumé | Liens | BibTeX | Étiquettes: Closed loop systems, Control methodology, Controllers, Digital control systems, Discrete – time systems, Discrete time control systems, Feedback control, Feedback controller, Feedforward filters, Leveling (machinery), Model uncertainties, Motion control, Reference signals, Robust control, Robust controller design, Robust feedback controllers, Robustness (control systems), Signal processing, Uncertainty analysis, Water tanks @article{Achnib2019c, A discrete-time robust controller design method is proposed for optimal tracking of future references in preview systems. In the context of preview systems, it is supposed that future values of the reference signal are available a number of time steps ahead. The objective is to design a control algorithm that minimizes a quadratic error between the reference and the output of the system and at the same time achieves a good level of the control signal. The proposed solution combines a robust feedback controller with a feedforward anticipative filter. The feedback controller’s purpose is to assure robustness of the closed-loop system to model uncertainties. Any robust control methodology can be used (such as μ-synthesis, qft, or crone control). The focus of this paper will be on the design of the feedforward action in order to introduce the anticipative effect with respect to known future values of the reference signal without hindering the robustness achieved through the feedback controller. As such, the model uncertainties are taken into account also in the design of the feedforward anticipative filter. The proposed solution is validated in simulation and on an experimental water tank level control system. © 2019 American Society of Mechanical Engineers (ASME). All rights reserved. |
