1. Vibration control device for steel tubular towers of Horizontal Axis Wind Turbines
Abstract This paper presents and discusses the design of a vibration control device for a 120 m high steel tubular tower of onshore Horizontal Axis Wind Turbine (HAWT). The tower is modeled using beam (own code), and shell and solid finite elements (via ANSYS). The Dynamic Vibration Absorber (DVA) is designed to be attached to the tower top, aiming to analyz

2. MULTIVARIABLE OPTIMAL CONTROL OF A HEAT EXCHANGER NETWORK WITH BYPASSES
Abstract Heat exchanger networks present an interesting control problem due to coupling among process streams. In this work, the linear quadratic regulator (LQR), a feedback optimal control technique, is used to control stream temperatures on a laboratory scale heat exchanger network, through bypass manipulation, in a multivariable system. The LQR design was

3. Utilização dos métodos SDRE e filtro de Kalman para o controle de atitude de simuladores de satélites / Application of SDRE and Kalman filter methods to attitude control of satellite simulators.
Space missions involving automatic procedures for big attitude maneuvers and control using new non-linear control techniques require from the satellite Attitude Control System (ACS) reliability, adequate performance and robustness. In that context, experimental validation of new equipment and/or non-linear control techniques through prototypes is the way to

9. Integrated structural/control optimization of a large space structure with articulation subject to the gravity-gradient torque.
Optimization has been playing a very important role in the orbit and attitude control, and structural design of spacecraft since the advent of the space era. It is well known that weight, space, energy, and time are among the most important constraints that guide the space missions planning. the optimization has a wide field of applications even if only the
