1. Design of Attitude Control Servomechanisms with Fluid Ring and CMG for Rigid Satellite
ABSTRACT: Satellites cover a wide range of space missions as remote sensing. Accomplishment of the mission depends on satellite's stability maintenance and direction. The main task of the attitude control system is to provide stability to the satellite against external disturbances. Such perturbations are caused due to aerodynamic drag, solar radiation and m

2. Projeto e implementação do controle de posição de uma antena de radar meteorológico através de servomecanismos. / Design and implementation of a weather-radar antenna position control using servomechanisms.
A classical radar antenna is basically composed of a primary source mounted at the focal point of a parabolic reflector. The illumination rule is established so that the desired beam-shape is attained, as precisely as possible. The physical motion of the set guarantees the coverage of the desired volume of exploitation. The actual text studies the design and

3. COMPARACIÓN DE MÉTODOS DE DISCRETIZACIÓN PARA EXTRUCTURAS DE CONTROL / A COMPARISON BETWEEN DISCRETIZATION METHODS FOR CONTROLLERS / COMPARAÇÃO ENTRE MÉTODOS DE DISCRETIZAÇÃO PARA ESTRUTURAS DE CONTROLE
Esta disertación presenta una comparación entre técnicas de discretización de controladores, considerando diferentes extructuras de control. Los tipos de sistemas estudiados en este trabajo de investigación son sistemas lineales, invariantes en el tiempo, determinísticos, causales y univariados. Se compara el desempeño de las técnicas de discretizaci

4. Dynamics, control and simulation of elastic space servomechanisms and manipulators.
This research results from a cooperation program between research institutes of Brazil (ITA - SÃo Josà dos Campos) and Germany (DLR - Oberpfaffenhofen). The global goal consists of three tasks: 1st) Analysisng the dynamics of elastic manipulators with emphasis for space applications. 2nd) Designing new adaptive control schemes for improving the manipulator

5. Uma contribuição ao estudo de não-linearidades na modelagem e controle de manipuladores
This work analyses the theory and simulation of Non-Linearitys found in the equations and robots control with one and two degrees of freedom. Simultaneously it is presented a detailed work on non linear system involving the development of Non Linear Controls for Industrial Manipulators. This process is moré advantageous than the classical linear controls. E

6. MÉTODOS INTERATIVOS PARA PROJETOS DE SERVOMECANISMO BASEADOS EM OTMIZAÇÃO H 2 / INTERATIVE METHODS FOR SERVOMECHANISM DESIGN BASED ON H2 OPTIMIZATION
Considera-se, neste trabalho, um problema de controle ótimo no qual o critério ( relativo à atenuação de sinais de perturbação) e a restrição (relativa à margem de estabilidade) são, respectivamente, normas e H2 e H(infinito) ponderadas de funções de transferência em malha fechada. Um procedimento iterativo para o obtenção de soluções aprox
