Texto completoIn a scenario of highly autonomous geostationary satellites, with self-assembly and self-maintenance capabilities, manipulator arms perturbations coupled with fuel slosh dynamics represents a significant risk of performance degradation for the satellite attitude and orbit control system. While passive fuel slosh damping solutions and manipulator arm disturbances compensators exist by their own, a unique active control solution capable of rejecting the perturbations while optimally preventing the actuators saturation is lacking and of great interest in the space industry for weight, cost and complexity of manufacturing reduction. This study explores the integration of $H_{infty}$-based robust control and model reference adaptive control techniques with reference governor schemes. The objective is to propose a unique control solution to guarantee precise satellite attitude control in the presence of unmodeled perturbations and actuator constraints. The theoretical advancements from this research also extend to scenarios such as handling propeller failures in quadrotors under state and input constraints and optimizing the design of the guidance modes for satellite missions like the CNES Microcarb mission

Texto completoIn this thesis we focus on the concept of parameter identification for different automatic fields. The first part of our work is devoted to the vector state estimation in combination with a parameter identification in order to obtain of a global knowledge of the system. Two different methods are introduced. On the one hand the parameter estimation law is obtained algebraically and converges in finite time. On the other hand the second parameter estimation law is dynamical and converges exponentially if the condition of Persistence Excitation is satisfied. Both of them are based on the Variable Structure Theory. Moreover we introduce a state feedback and dynamical control which is robust with respect to time-varying parameter perturbations. The robust behaviour is proven mathematically by using one specific property of the Variable Structure Theory. A comparison of the proposed method with well-known classical algorithms is introduced. In view of industrial applications and in order to limit the number of sensors we relax the condition on the feedback control and we extend it to output feedback by considering some backstepping aspects. Finally we study the problem of identification for nonlinear systems in which the parameters enter nonlinearly in the model's equations. We introduce a parameter identification which is satisfied locally in the parameter space and converges exponentially if the Persistence of Excitation is verified. This dynamical parameter estimation law is coupled with an adaptive state feedback control based on the Variable Structure Theory

Texto completoObservers and output regulation are two central topics in nonlinear control system theory. Although many researchers have devoted their attention to these issues for more than 30 years, there are still many open questions. In the observer theory a key role is played by the so called high-gain observers. The purpose of the first part of the thesis is to study novel techniques which allow to overcome or at least to mitigate some of the main drawbacks characterizing this class of observers. We propose a novel class of high-gain observers, denoted as ``low-power'', which allows to overcome numerical problems, to avoid the peaking phenomenon and to improve the sensitivity properties to high-frequency measurement noise. The second part of the thesis addresses the output regulation problem, solved for linear systems during the 70's by Francis and Wonham who coined the celebrated ``internal model principle''. Constructive solutions have also been proposed in the nonlinear framework but under restrictive assumptions that reduce the class of systems to which this methodology can be applied. In this thesis we focus on the output regulation problem in presence of periodic disturbances and we propose a novel approach which allows to consider a broader class of nonlinear systems. The resulting design is robust in the sense defined by Francis and Wonham
