1. Development, implementation and performance evaluation of a self-tuning regulator adaptive controller applied to a FCC process / Desenvolvimento, implementação e avaliação de desempenho de um controlador adaptativo do tipo self-tuning regulator aplicado a um processo FCC
This work had as main objective the development and implementation of an selftuning regulator (STR) adaptive controller, with subsequent comparison of its performance with a PID (proportional-integral-derivative) controller and two predictive controllers, namely a predictive based on artificial neural networks (MPC-ANN) and a dynamic matrix controller (DMC).

2. A fly-by-wire rudder control system design using multiobjective optimization.
This work aims to demonstrate an approach to design a fly-by-wire mobile surface control system for a commercial jet employing multiobjective optimization techniques. This approach consists on sizing a set of design parameters of the control system based on model simulation and response analysis coupled with optimization algorithms in a multiobjective design

3. CONTROLE POR APRENDIZADO DE SISTEMAS SERVO: HIDRÁULICOS DE ALTA FREQÜÊNCIA / LEARNING CONTROL OF HIGH FREQUENCY SERVO: HYDRAULIC SYSTEMS
Hydraulic systems are used where relatively high forces and torques are required, or when high response speeds are necessary. They are used in industrial systems, robotics, movement simulators, automated plants, ore exploration, presses, and especially in fatigue testing systems. Fatigue tests are usually performed on servo-hydraulic systems, in order to pre

4. Modeling and identification of a fly-by-wire control system.
This work investigates the system identification and modeling techniques applied to a fly-by-wire system for pitch control of a commercial jet aircraft. The objective of the work is to build a model based on system identification techniques and generic modeling of the system, therefore using the "grey box" approach. The identification data was obtained from

5. Projeto, construção e avaliação de uma servovalvula dosadora para sistemas de aplicação de fertilizantes liquidos a taxas variaveis
This work had as aim to project, to build and to evaluate a flow control servo-valve for liquid fertilizer application in variable rates, as well as to conceive a system with capacity for formulation and dosage in which the valve can operate. It was conceived a system capable to work with three concentrate formulations simultaneously, using three independent

6. The Newmarket pump: a new suction pump for external negative pressure ventilation.
A new electronically controlled pump has been developed for use with a cuirass in providing external negative pressure ventilation. It is smaller, lighter, and more versatile than currently available pumps and operates on a servo principle. A rotary valve between the pump and the cuirass varies the rate of extraction of air from the cuirass. The pressure wit
