1. CONTRIBUTION TO THE STUDY OF PERMANENT MAGNET SYNCHRONOUS ADVANCED DRIVE: APPROACH BASED ON HIGHER ORDER SLIDING MODES CONTROL / CONTRIBUIÇÃO AO ESTUDO DO ACIONAMENTO AVANÇADO DO MOTOR SÍNCRONO DE ÍMÃS PERMANENTES: ABORDAGEM BASEADA NOS MODOS DESLIZANTES DE ORDEM SUPERIOR
This work presents a study of first and second order sliding mode controllers applied to permanent magnet synchronous motor.The aim is a theoretical study and an experimental implementation, using the DSP TMS320F2812 platform, of two second order sliding mode controllers. In addiction a study about the first order sliding mode is presented. The inclusion of

2. AnÃlise de tÃcnicas de controle de conversores conectados a redes elÃtricas
This work presents a performance analysis of some control techniques applied to voltage-source converters during transients in the power systems. In this sense, in all the computational simulations the converter was considered to be connected to the CHESF (Brazilian federal power utility) east system, which was represented in ATP. The transmission lines conn

3. Estabilidade e robustez de um controlador adaptativo indireto por um modelo de referência e estrutura variável / Robustness and stability analysis of an indirect variable structure model reference adaptive controller
In this thesis, it is developed the robustness and stability analysis of a variable structure model reference adaptive controller considering the presence of disturbances and unmodeled dynamics. The controller is applied to uncertain, monovariable, linear time-invariant plants with relative degree one, and its development is based on the indirect adaptive co

4. Controle em modos deslizantes do servomotor C.A.
This work presents a study about non-continuous sliding modes control applied to Permanent Magnetic AC motor (PMAC), also called AC Servomotor. The two main objectives of this work are: to analise the robustness of the technique related to load disturbance and variations in the windings resistance; and to study alternative ways to reduce chattering. The firs

5. APLICACIÓN DE ELEMENTOS FINITOS DE INTERFACE A MODELOS DE MODOS MIXTOS DE FISURAS / MODELING OF MIXED MODE CRACKS IN MASONRY STRUCTURES USING INTERFACE FINITE ELEMENTS / APLICAÇÃO DE ELEMENTOS FINITOS DE INTERFACE À MODELAGEM DE MODOS MISTOS DE FISSURAÇÃO
Since masonry is a widely employed material, it is fundamental to better characterize its structural performance and extend its use beyond functional applications (separation of environments). In this work a finite element model for masonry structures is presented. By using a sophisticated numerical tool based on the finite element method, associated to suit
