Abstract:
This text presents the development of a four-degree-of-freedom (4DOF) quadcopter prototype that allows the vehicle to rotate around the three axes (yaw, pitch and roll) and linear movement along z-axis (altitude). The goal is to obtain a prototype bench that uses a good amount of components used in commercial quadcopters (sensors and actuators) and use it to apply attitude and altitude controllers, using techniques such as PID, LQR and Sliding-Mode. Starting from the system modeling, its specifications are shown followed by listing the components used, finishing with the development of the con

Abstract:
In this work, a unicycle system with reaction wheel is presented, considering the construction, the modeling, the design and test of the controllers. Firstly, a mechanical model considering a tridimensional computer aided design (3D CAD) is built in order to assist the construction and, after that, the modeling using the Lagrange method. In this work, linear controllers are designed and, therefore, the linearization of the system is done by the Jacobian, that is, assuming small variations around the equilibrium point. In this situation, there is no coupling between the pitch and the roll angle

Abstract:
Downsizing and turbocharging of engines provide a way to meet increasing demands for efficiency and performance in the automotive industry. An engine design is a result of compromises, e.g. the selection of charging system, and the trend is to reduce these compromises by increasing system complexity. Models have come to play a central role to handle this rise in complexity, and are used for simulation, system optimization and control synthesis. The models should describe the entire operating range, be capable of extrapolation, be easily parameterizable, and wide cover a range of applications.

Most smart actuators exhibit rate-dependant hysteresis when the working frequency is higher than 5Hz. Although the Preisach model has been a very powerful tool to model the static hysteresis, it cannot be directly used to model the dynamic hysteresis. Some researchers have proposed various generalizations of the Preisach operator to model the rate-dependant hysteresis, however, most of them are application-dependant and only valid for low frequency range. In this thesis, a first-order dynamic relay operator is proposed. It is then used to build a novel dynamic Preisach model. It can be used to

Turbocharging is a way to stay competitive on the market where there are increasing demands on fuel consumption and engine performance.

Before such a controller can be designed, the system has to also be represented as an LPV system.

Abstract:
In this dissertation I assessed three distinct policy questions: the implications of introducing a new tuberculosis diagnostic in southern Africa, the potential value of research related to HIV treatment policy in South Africa, and the causal effect of state cigarette taxes imposed between 1996 and 2013 on health outcomes in the United States.

Abstract:
This master’s thesis project from the Department of Mathematics at KTH, Royal Institute of Technology, Stockholm, Sweden was carried out at Saab Dynamics, Linköping, Sweden. In this thesis, an octocopter was studied, which is a multirotor vehicle, a rotorcraft with more than two rotors. Multirotors have recently become very popular and have various interesting applications needing further research. Since the market for powerful credit-card-sized computers is continuously increasing, the development and research of multirotors is simplified. The main purpose of this thesis project was to develo

Abstract:
<p>Cables are used in various fields like construction, sports, communication, and transportation. Two important fields where cables are used for this research are transportation and high-voltage power lines. In the field of transportation, cables are used in cable-riding systems like cable cars, tramways, and gondola lifts. Vibration is induced in these systems. These vibrations are undesirable. </p><p> High-voltage power line cables are important part of our lives. Inspection of these power lines is necessary to eliminate the risk of power outages. Earlier power lines were inspected by ski
