Texto completoThis manuscript deals with robust direct adaptive control, and its application to CNES microsatellites attitude control. After listing the different types of time-varying controllers, we recall the characteristics of direct adaptive control. In particular, we recall that the knowledge of a stabilizing static output feedback is sufficient to design a direct adaptive controller. In parallel, we introduce the descriptor system theory. Modelizing a system into descriptor form is not usual but fits well with robust direct adaptive control. Starting from existing results about adaptive control and descriptor system theory, we provide an LMI based method which allows to compute, with the knowledge of a stabilizing static output feedback, the parameters of a stabilizing direct adaptive controller. A first result proves that the adaptive controller is at least as robust as the static output feedback. The second result allows to prove improved robustness at the expense of relaxing stability of the equilibrium point to practical stability, that is convergence to a neighborhood of the equilibrium. Then, we provide a method, LMI based as well, which allows to design a robust direct adaptive controller which has a better level of rejection of the perturbations than the static output feedback from which it is designed. All these theoretical results are applied to the attitude control of CNES microsatellites. We design a controller which stabilizes the attitude of the satellite whatever the value of its inertia. This attitude controller can also avoid the satellite reaction wheels to saturate. We design another robust adaptive attitude controller which has a better level of rejection of the perturbations than the static controller which is currently implemented aboard CNES satellites. Finally, we validate all the results of this manuscript by simulating on a AOCS CNES simulator the deployment of the satellite masts and some guiding jumps

Texto completoThis manuscript considers time varying control, with a strong emphasis on a satellite attitude control application. Three types of control structures have been studied: a switch-based approach, LPV control and direct adaptive control. In this last field we have introduced new theoretical results which allow structuring the gain and the adaptation law. The results have been validated in simulation and are currently tested on board a satellite. Starting from the switch-based control law currently implemented on the Myriade satellites, a first part of our work isdedicated to LPV control. Based on the specification of the control objectives by using of an LPV reference model, our approach allows obtaining new control algorithms expressed within this framework. The simulations carried out with theLPV algorithms obtained by using this method show that they meet the needs of our application. Nonetheless, the choice of a reference model proves to be difficult. This obstacle has been surpassed by using direct adaptive control. In this approach, specifications regarding the timevarying behaviour are added through constraints on the laws defining the control gains adaptation. We thus introduce anew synthesis method, based on which structured adaptive control laws are obtained. Stability proofs are established based on tools of the Lyapunov theory.The results obtained on a complete simulator show the interest of using such adaptive algorithms, which allow in particular to modify the satellite dynamics depending on the available capacity of the actuators. Based on these positive results, a fight-test campaign on the PICARD satellite is underway

Texto completoFrom the early days of the space age, satellites were considered as a solution for many scientific and practical tasks, notably astronomy, Earth observation and telecommunication. Traditionally and to the present day, mostly large satellites with a mass from several hundred kilograms to several tons are used for these purposes. The key success factor of such space missions is a fine control of satellite’s attitude. To ensure high pointing accuracy, satellite’s attitude determination and control subsystem (ADCS) relies on precise three-dimensional attitude data provided by an opto-electronic instrument called star tracker (ST). The use of stars as reference objects allows to determine the satellite’s attitude in real time with an arc-second precision.A significant work on miniaturization of satellite subsystems carried out in the past twenty years, allows us today to build a complete satellite with a mass of only a few kilograms. An increasing number of successful nano- and picosatellite missions demonstrates constantly improving capabilities of modern miniaturized satellite platforms. However, until recently, integration of a star tracker into a nanosatellite was not possible because of a large size of the device and relatively high power consumption, and that limited possible applications of the nanosatellites. In attempt to change the situation, in the last five years about a dozen of miniature star tracker prototypes, suitable for nanosatellite platforms, were proposed by various developers. Some were successfully tested in space, yet most prototypes, including the tiniest ones, are still at the development stage.A modern star tracker is a system, that can be represented as two modules, a digital camera module and a processing module. Use of a compact camera lens and a small-size image sensor allows to significantly reduce overall mass and size of the device, and at the same time, may cause significant image quality deterioration, due to increased distortion, uncompensated spherical and chromatic aberration, lower signal-to-noise ratio (SNR) and overall lower light sensitivity of the camera module. Thus, embedded software of the processing module, responsible for pre-processing, star identification and attitude calculation, should take into account the limitations imposed by the miniaturization of the camera module. At the same time, hardware architecture of the processing module should have the capacity to perform necessary correction of the digital image in real time, and to ensure stability and expected performance of the star identification and attitude calculation routines.The goal of hardware and software prototyping of a miniature star tracker system, carried out in this work, is to evaluate various design solutions, that could be brought into the camera or into the processing module, in order to help the miniaturization of the system. Another goal is to analyze the impact of every hardware and software component on the overall performance of a miniaturized star tracker system. Among the list of star tracker characteristics, the initial attitude estimation time and the attitude output rate became the focus of the research. Current work addresses possible performance bottlenecks, that may appear on any step of star tracker operation, from capturing starlight to calculation of components of the attitude quaternion, and proposes an original solution to speed-up the star identification routine

Texto completoAfter the launch of the first artificial Earth satellite in 1957, the evolution of various technologies has fostered the miniaturization of satellites. In 1999, the development of standardized modular satellites with masses limited to a few kilograms, called CubeSats, was initiated by a joint effort of California Polytechnic State University and Stanford University. Since then, CubeSats became a widespread and significant trend, due to a number of available off-the-shelf low cost components.In last years, the number of launched CubeSats constantly grows, but less than half of all CubeSat missions achieved their goals (either partly or completely). The analysis of these failures shows that the most evident cause is a lack of proper component-level and system-level CubeSat testing. An especially challenging task is Hardware-In-the-Loop (HIL) tests of the Attitude Determination and Control System (ADCS). A system devoted to these tests shall offer reliable simulations of the space environment and allow realistic CubeSat motions. The most relevant approach to provide a satellite with such test conditions consists in using air bearing platforms. However, the possible satellite motions are strictly constrained because of geometrical limitations, which are inherent in the air bearing platforms. Despite 15 years of CubeSat history, the list of the air bearing platforms suitable for CubeSat ADCS test is very limited.This thesis is devoted to the design and development of an air bearing testbed for CubeSat ADCS HIL testing. The main novelty of the proposed testbed design consists in using four air bearings instead of one and in utilizing a robotic arm, which allows potentially unconstrained CubeSat motions. Besides the testbed design principle, this thesis deals with the related issues of the determination of the CubeSat orientation by means of contactless measurements, and of the behavior of the air bearings, as well as with the need of a mass balancing method.In order to verify the feasibility of the proposed design, a prototype of the testbed is developed and tested. Several modifications aimed at simplifying the structure and at shortening the fabrication timeline have been made. For this reason, the Adept Viper s650 robot is involved in place of a custom-designed 4DoF robotic arm. A control strategy is proposed in order to provide the robot with a proper motion to follow the CubeSat orientation. Finally, the obtained results are presented and the overall assessment of the proposed testbed is put into perspective

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 completoThis manuscript reviews contributions to the development of systematic methods for analysis and control of periodic uncertain systems. An important part of this thesis is also dedicated to the design of attitude control systems for satellites whose dynamics is naturally represented as a periodic model subject to uncertainties. The first part is devoted to the developpement of a unifying presentation of the analysis and synthesis results of periodic, uncertain and discrete-time models via methods relying on linear matrix inequalities (LMI) and based on Lyapunov theory. Subsequently, the focus is on a new class of periodic control laws with memory for which the control input is constructed using history of the states of the system kept in memory. Numerical experiments show that these new degrees of freedom can outperformed the existing results. The second part deals with periodic and robustness aspects of attitude control of a satellite using magnetorquers. These actuators use the geomagnetic field that varies periodically along the orbital trajectory. Different control strategies are implemented and compared with one another with the constant concern of taking the main limitations of the actuators into account. This approach leads to a new control law regulating the momentum of the reaction wheels without disturbing attitude control for which the control effort is shared by all actuators
