Texto completo da fonteThis PHD thesis focuses on static analysis of programs by type inference in order to detect program errors before their execution. More precisely, we focus hear in the field of sub-typing, where program properties are described by sets of constraints of the form (t1 <= t2). Our verification mechanisms are based on the aggregation of sub-typing constraints and checking of their compatibility by saturation. The base language on which we define our type systems is an ML-like language provided with variants and pattern matching. We starts by defining a formalism to express our type systems thanks to inference rules. This formalism has the advantage to be sufficiently flexible to allow proving validity and termination properties of our systems, and sufficiently precise to allow a systematic derivation of our inference rules into a runnable typer. After the definition of a base type system for our language, we present three novel extensions: * An improvement of type inference for the pattern matching based on the addition of the "or" operator between sub-typing constraints. This operator allow to express a link, in each cases of a match, between the pattern and the constraints generated at typing time of the case expression. This allows us to refine the type of some functions, and then to accept more valid programs. * A new implementation of the generalization mechanism. This allows to distinguish constraints associated to the different occurrences of a function parameter in its body. Thanks to this mechanism, the "let" construction from ML is in particular obsolete. By mixing this extension with the first one, we obtain a type system able to encode "objects" without any additional language construction. * A formalization of GADT based on an novel implementation of existential type variables. In addition to be compatible with the sub-typing context of this thesis, this alternative to GADT has the advantage to improve type inference. As a consequence, most of type annotations, usually required in the presence of GADT, are now optional. Despite the fact that it is possible to directly derive an implementation of our type systems from their rules, that is principally interesting for their comprehension and prototyping, the effectiveness of such typer is insufficient to analyze real world programs. This is principally due to the extensions we provide to the language of constraints, and in particular to the "or" and "not" operators. At then end, we present multiple techniques we used in our implementation to extend the scalability of our analysis

Texto completo da fonteThis thesis is about the stabilization of nonlinear systems with partial measurements and constrained input. The two first chapters deals with saturated inputs in the contex of infinite-dimensional systems for nonlinear abstract equations and for a particular partial differential equation, the Korteweg-de Vries equation. The third chapter provides an output feedback design for two Korteweg-de Vries equations using the backstepping method. The fourth chapter is about the output feedback design of nonlinear finite-dimensional systems for which there exists a hybrid controller. A high-gain observer strategy is used

Texto completo da fonteMost physical systems are subject to control constraints. Indeed, these constraints can lead to the degradation of performances and even instability of closed-loop systems. In this context, the main objective of this thesis is to develop adaptive fuzzy control laws for nonlinear systems in the presence of saturation constraints and applying them to the diesel engine system. The objective is to control the three actuators of the air loop of the diesel engine, namely: the Exhaust Gas Recirculation (EGR), the Variable Geometry Turbine (VGT) and the Throttle. The idea is to track a given reference signals which are chosen in order to optimize the pollutant emissions and the fuel consumption. In this thesis, two models have been adopted, a model with two inputs and two outputs in which the Throttle is assumed to be totally opened and a three input three output model. These models describe the significant parameters of the system, such that: the pressure of the intake manifold, the pressure of the exhaust manifold and the compressor power. The proposed algorithms are validated by simulation and using the AMESim simulator

Texto completo da fonteThis thesis concerns the modeling of concrete and concrete structures subjected to stresses ranging from quasi-static to dynamic loading, taking into account the presence of free water in pores. The objective is the development of a predictive simulation tool capable of describing the behavior of concrete and concrete structures, taking into account the effects of saturation ratio. The choice of discrete elements for modeling is justified by the discontinuous phenomena that appear in the concrete, such as cracking, fragmentation, spalling and scabbing. Discrete Elements can reproduce reliably and efficiently the local discontinuous behavior and the overall response of the structure.The first part of this work concerns the simulation of quasi-static tests under uniaxial and highly confined triaxial loadings, taking into account the compaction phenomenon. The effects of the free water contained in the pores are taken into account by introducing a dependency between the water saturation level and the inelastic deformation. The identification process of the model parameters is presented. Finally, the model is validated by reproducing the quasi-static behavior of concrete in different tests.The second part of this work concerns the dynamic behavior of concrete. The aim is to extend the validation of the model by simulating impact tests on concrete slabs of different thickness. The dynamic effects are taken into account and impact simulations on concrete slabs of different thickness are made. The results are in good agreement with experimental results
