Testo completoTwo techniques are used to verify if real-time tasks meet their deadlines : schedulability tests that return a binary result (schedulable or not) and the calculation of the response times (Response Time Analysis - RTA) which determines the length of the longest interval between the release instant and the completion of a task. Both approaches have a pseudo-polynomial time complexity and please note that no polynomial time algorithm is known. In this context, they are not particularly suitable for interactive design of real-time systems or to analyze distributed systems using an holistic analysis. In such scenarios, a pseudo-polynomial time algorithm is slow, since the computations of the task response times are performed many times. Moreover, for some real time systems, such as the control-command systems, it is necessary to know the task worst-case response times and not only the binary decision on the tasks schedulability. In this context, it may be acceptable to use a faster algorithm which provides an approximate analysis instead of the analysis based on exact calculations. As these approximations will produce pessimism in the decision process, it is desirable to quantify this pessimism in such a way as to define a compromise between computation time and resource requirement of processor. That is the reason why, in this work, we propose efficient algorithms to compute upper bounds of worst-case response times and we present results on their qualities in the worst-case (competitive analysis resource augmentation) and in the average (simulations)
Lopez, Ramirez Francisco. "Control and estimation in finite-time and in fixed-time via implicit Lyapunov functions". Thesis, Lille 1, 2018. http://www.theses.fr/2018LIL1I063/document.
Testo completoThis work presents new results on analysis and synthesis of finite-time and fixed-time stable systems, a type of dynamical systems where exact convergence to an equilibrium point is guaranteed in a finite amount of time. In the case of fixed-time stable system, this is moreover achieved with an upper bound on the settling-time that does not depend on the system’s initial condition.Chapters 2 and 3 focus on theoretical contributions; the former presents necessary and sufficient conditions for fixed-time stability of continuous autonomous systems whereas the latter introduces a framework that gathers ISS Lyapunov functions, finite-time and fixed-time stability analysis and the implicit Lyapunov function approach in order to study and determine the robustness of this type of systems.Chapters 4 and 5 deal with more practical aspects, more precisely, the synthesis of finite-time and fixed-time controllers and observers. In Chapter 4, finite-time and fixed-time convergent observers are designed for linear MIMO systems using the implicit approach. In Chapter 5, homogeneity properties and the implicit approach are used to design a fixed-time output controller for the chain of integrators. The results obtained were verified by numerical simulations and Chapter 4 includes performance tests on a rotary pendulum
Dagbagi, Mohamed. "Simulation temps-réel embarquée de systèmes électriques au moyen de FPGA". Thesis, Cergy-Pontoise, 2015. http://www.theses.fr/2015CERG0808/document.
Testo completoThe aim of this thesis work is to develop an IP-Library of FPGA-based embedded real-time simulator IPs (Intellectual Properties) that simulate different elements of an electrical system. These IPs have been designed to be used not only for Hardware-In-the-Loop (HIL) testing of digital controllers but also for low cost embedded control applications, where the simulator IP and the controller are both implemented and run altogether in the same FPGA device. This emerging class of real-time simulators is expected to be more and more included in the next generation of digital controllers. Indeed, such embedded real-time simulator IPs can be advantageously embedded within digital controllers to ensure functions like observation, estimation, diagnostic or health-monitoring. Conversely to the HIL case, the main challenge when designing such simulator IPs is to cope with their complexity having in mind that, in the case of embedded systems, the available hardware resources are limited due to the cost. Furthermore, this challenge is strengthened by the need of very short simulation time-steps which is typically the case when simulating power converters.To develop these IPs, dedicated design guidelines have been proposed to be followed to manage the complexity of these simulator IPs (model solver, numerical solver, time-step, data conditioning) with regards to the timing and the area/cost constraints (computation time limit, limited hardware resources …).The simulators IPs to be developed have been organized into two main categories: those dedicated to electromagnetic elements of an electrical system and those dedicated to their switching elements.The first category gathers elements where electric, magnetic phenomena are modelized in addition to mechanical phenomena (for moving systems) and potentially thermal phenomena. Three cases are dealt with: the embedded real-time simulator of a three-phase synchronous machine, the one of a three-phase induction machine and the one of a brushless synchronous generator. Also, the advantages of using delta transformation to improve the stability of the numerical solver when short simulation time-step and fixed-point (with limited data precision) are used, have been studied.The second category concerns switching elements such as power converters where switching events are considered. Here again, several converter topologies have been studied: a half-wave rectifier, a buck DC-DC converter, a bidirectional buck DC-DC converter, a H-bridge DC-DC converter, a single-phase H-bridge DC-AC converter, a three-phase voltage source inverter, a three-phase diode rectifier and a three-phase PWM rectifier. For all these IPs, the Associated Discrete Circuit (ADC) modeling approach is adopted.The embedded real-time simulator IP of the three-phase PWM rectifier has been applied in the context of an embedded application. The latter consists of a fault-tolerant control of a grid-connected voltage source rectifier. Thus, this simulator IP is associated with the one of a three-phase RL-filter and are both implemented within the rectifier controller to estimate the grid currents. These currents are injected in the controller in the case of a current sensor fault. The ability of this estimator to guarantee the service continuity in the case of faults is validated through HIL tests and experiments

Testo completoIn this thesis, low-complexity algorithms and architectures for CO-OFDM systems are explored. First, low-complexity algorithms for estimation of timing and carrier frequency offset (CFO) in dispersive channel are studied. A novel low-complexity timing synchro- nization algorithm, which can withstand large amount of dispersive delay, is proposed and compared with previous proposals. Then, the problem of realization of low-complexity parallel architecture is studied. A generalized scalable parallel architecture, which can be used to realize any auto-correlation algorithm, is proposed. It is then extended to handle multiple parallel samples from ADC and provide outputs, which can match the input ADC rate. The scalability of the architecture for higher number of parallel outputs and different kinds of auto-correlation algorithms is explored. An algorithm-architecture approach is then applied to the entire CO-OFDM transceiver chain. At the transmitter side, radix-22 algorithm for IFFT is chosen and parallel Mul- tipath Delay Commutator (MDC) Feed-forward (FF) architecture is designed which con- sumes lesser resources compared to MDC FF architectures of radix-2/4. At the receiver side, efficient algorithm for Integer CFO estimation is adopted and efficiently realized with- out the use of complex multipliers. Reduction in complexity is achieved due to efficient architectures for timing synchronization, FFT and Integer CFO estimation. Fixed-point analysis for the entire transceiver chain is done to find fixed-point sensitive blocks, which affect bit error rate (BER) significantly. The algorithms proposed are validated using opti- cal experiments by the help of arbitrary waveform generator (AWG) at the transmitter and digital storage oscilloscope (DSO) and Matlab at the receiver. BER plots are used to show the validity of the system built. Hardware implementation of the proposed synchronization algorithm is validated using real-time FPGA platform

Testo completoThe continuous integration of new functionality increases the complexity of embedded systems, while each functionality might impose precedence constraints between the programs fulfilling it. In addition, the prevalence of several processors may create the illusion of higher computation capacity easing the associated scheduling problem. However, this capacity is not exploitable in critical real time systems because of the increased variability of the execution times due to processor features designed to provide excellent average time behavior and not necessarily ensuring small worst case bounds. This difficulty is added to the existence of scheduling anomalies when the systems are built a top of multi-core processors. In this thesis, we consider partitioned scheduling of DAG tasks defining precedence constraints. The variability of execution times is described by probability distributions. We propose a Response Time Analysis (RTA) based on iterative equations and probabilistic operators for independent distributions. For dependent distributions, we model them using Bayesian network. We also use C-space representation combined with SVM classification to estimate the schedulability probability. Moreover, we provide techniques to define priority and sub-task partitioning in a way to increase parallelism. We also decrease analysis complexity by reducing size of graph without altering the precedence structures

Testo completoDans la deuxième partie, consacrée aux mélanges sous-déterminés instantanés et convolutifs, nous cherchons aussi à étendre l'algorithme FastICA en nous basant sur le concept de séparation différentielle. Nous proposons des procédures de blanchiment différentiel des observations qui permettent l'emploi d'itérations à point fixe pour séparer entre elles des sources dites utiles. En convolutif, les contributions sont estimées au moyen d'un filtre de Wiener différentiel non-causal.
La troisième partie, consacrée aux mélanges instantanés de sources contenant un grand nombre d'échantillons, met d'abord en évidence une limitation de l'algorithme FastICA, qui, à chaque itération d'optimisation, calcule des statistiques sur l'ensemble des échantillons disponibles. Le critère du kurtosis étant polynômial relativement aux coefficients d'extraction, nous proposons une procédure d'identification de ce polynôme qui permet d'effectuer l'optimisation dans un espace de calcul moins gourmand. Ce principe est ensuite appliqué aux mélanges instantanés sous-déterminés.
