Parameter uncertainty quantification seeks to determine both estimates and uncertainty regarding estimates of model parameters. Example of model parameters can include physical properties such as density, growth rates, or even deblurred images. Previous work has shown that replacing data with a surrogate model can provide promising estimates with low uncertainty. We extend the previous methods in the specific field of linear models. Theoretical results are tested on simulated computed tomography problems.

As well as studying the regularization of the nonparametric part, we also mention theoretically the regularization of the parametric part. Furthermore, we make a comparison between Infinite Kernel Learning (IKL) and Tikhonov regularization by using two data sets, with the difference consisting in the (non-)homogeneity of the data set. The thesis concludes with an outlook on future research.

Повний текст джерелаFor variable-speed wind energy conversion systems, control objectives may be different in partial and full load regions (or in low and high wind speed regions). Typical control objectives are to maximize the energy capture in low wind speeds, and to maintain the generated power and the rotational turbine speed within safety limits during high wind speeds. In such a case, it is difficult to design a single robust controller covering both partial load and full load conditions. This paper presents a systematic switching control method for a variable-speed variable-pitch wind turbine over a wide wind speed region. The whole framework is based on the linear parameter-varying (LPV) control theory, which is an extension of robust control for linear systems to nonlinear ones.
Two LPV controllers are designed, each suitable in a different wind speed region. A hysteresis switching logic is applied to guarantee the stability when the switching event occurs between the two controllers. Nonlinear simulations are conducted to demonstrate the proposed control scheme.

This work addresses the modeling and the linear parameter-varying (LPV) system identification of a coupled two-tank system (TTS). The system is a multiple input multiple output (MIMO) with two inputs and two outputs. In order to obtain a suitable model for this system, a first-principle approach based on the mass balance principle is followed. It turns out that the modeling process was driven by the geometrical shape of the tanks. Thus, most of its parameters are based on the tanks’ dimensions. When it comes to the LPV identification, several methods are presented ranging from the classical results from the regression approach to the current support vector machines (SVM) based methods. All the identification algorithms presented are extended in order to cope with the MIMO systems. Additionally, a method based on instrumental variables support vector machines was adapted from the general nonlinear case to the LPV case. A new LPV model with two independent scheduling variables is proposed driven by prior knowledge on the process model. The results obtained with this new LPV model have showed a good performance in describing the TTS behavior. Furthermore, they were better than an LPV model considering only a single scheduling variable.
Este trabalho lida com a modelagem e identificação com abordagem de sistemas com parâmetros variantes (LPV) de um sistema de dois tanques acoplados (TTS). Esse sistema é do tipo múltipla entrada múltipla saída (MIMO) com duas entradas e duas saídas. Com a finalidade de obter um modelo adequado para esse sistema, é feita uma abordagem fenomenológica baseada no princípio do balanço de massa. Descobre-se que o processo de modelagem é dependente da forma geométrica dos tanques. Assim, a maioria dos seus parâmetros são baseados nas dimensões dos tanques. Quando se trata de identificação de sistemas LPV, vários métodos são apresentados desde os resultados clássicos baseados em regressão até os métodos atuais baseados em máquinas de vetor de suporte. Todos os algoritmos de identificação apresentados são estendidos para lidar com sistemas MIMO. Além disso, um método baseado em variáveis instrumentais com máquinas de vetor de suporte foi adaptado do caso não linear geral para o caso LPV. Um novo modelo LPV com duas variáveis de scheduling é proposto baseado em conhecimento a priori no modelo do processo. Os resultados obtidos com esse novo modelo LPV mostraram bom desempenho ao descrever o comportamento do sistema de dois tanques. Ademais, eles foram melhores do que um modelo LPV considerando apenas uma variável de scheduling.

Vibration in helicopters can have a significant impact on their utility, maintenance, weight, performance, and cost of operation. This thesis focuses on the design of a vibration reduction controller that is effective throughout the flight envelope of the helicopter, in spite of variations in vibration levels and dynamics with flight condition. Analysis of a UH-60 Black Hawk helicopter modeled in the Rotorcraft Comprehensive Analysis System (RCAS) aeromechanical simulation environment indicates that the steady state vibration levels and the helicopter dynamics depend primarily on the advance ratio. Two baseline vibration controllers are developed, specifically the Continuous Time Higher Harmonic Controller (CTHHC) and an H[subscript of infinity] based controller, over a range of advance ratios. The unique controller developed in this thesis uses the Linear Parameter Varying (LPV) synthesis method, which provides performance and stability guarantees over the advance ratio parameter space. The three controllers are evaluated in the RCAS environment at fixed and maneuvering flight conditions. The results indicate that the full envelope controller designed using the LPV method exhibits increased performance over the CTHHC and H[subscript of infinity] controllers.

Повний текст джерелаIt is challenging to design a controller for a wind turbine system because of its nonlinear time-varying dynamics. To resolve this issue, linear parameter-varying (LPV) control theory has been applied in the past 10years to deal with nonlinear and wind-speed-dependent dynamics. Before applying the LPV control method, it is required to transform the nonlinear model of the system to an LPV model. The main objectives of this research are to model a 5-megawatt (MW) Reference Wind Turbine for Offshore System as an LPV system, develop a nonlinear wind turbine simulator using MATLAB/Simulink to validate the LPV model, and conduct a preliminary study on LPV control design to test the simulator, which will be used in the future research for applying different LPV control techniques, such as switching LPV control, LPV anti-windup control, and others.

Повний текст джерелаThe work presented in this dissertation is related to the Hinf-LPV-controller orderReduction. This latter consists of the design of a robust reduced-order LPV-controller for LPV-systems. The order reduction issue has been very fairly investigated. However, the case of LPV-control design is slightly discussed. This thesis focuses primarily on two topics: How to obtain an LPV-reduced-order controller even the high order generated by the classical synthesis and how this reduced order controller can deal with a practical engineering problem (semi-active suspension control). In view of this, the order-reduction topic and the Hinf-synthesis theory have been widely studied in this thesis. This study, has allowed the development of a new method forH1-LPV-controller order reduction

Resumo: Neste trabalho discutimos a detecção de observações influentes em modelos simétricos lineares e não lineares. Em primeiro lugar é realizado um estudo de simulação para avaliar o desempenho de três métodos de estimação em dados gerados por quatro situações: sem observações influentes, com outliers na variável resposta, com observações influentes de média alavancagem e com observações influentes de alta alavancagem. São analisados dois métodos de máxima verossimilhança e um método robusto. Foram considerados modelos de regressão linear e não linear com erros logísticos tipo II e t-Student. Em segundo lugar é discutida detecção de observações influentes mediante a distância de Cook generalizada, a estatística de Peña e a estatística de Andrews-Pregibon. Em particular é discutida a conveniência de utilizar a metodologia de limiares para caracterizar uma observação como influente ou não influente, assim como o efeito da estimação de parâmetros na construção de limiares. Estas medidas foram aplicadas a conjuntos de dados reais e simulados considerando o ajuste de alguns modelos simétricos com uma adaptação no método de estimação scoring de Fisher
Abstract: We discuss the detection of influential observations in symmetrical linear and nonlinear regression models. First a simulation study is conducted to evaluate the performance of three estimation methods on data generated by four situations: without influential observations with outliers in the response variable, with influential observations average leverage and influential observations with high leverage. Two methods of maximum likelihood and robust method are analyzed. We considered linear and nonlinear regression models with logistic-II and Student-t errors. Secondly detection of influential observations by generalized Cook's distance, the statistic PeÃ?a and Andrews - Pregibon statistic is discussed. In particular the convenience of using the methodology to characterize a threshold observation as influential or not influential, as well as the effect of parameter estimation in the construction of thresholds is discussed. These measures were applied to sets of real and simulated data considering the fit of some symmetrical regression models with an adaptation estimation method of Fisher scoring
