Design and Development of a Multi-Mode, Two-Wheeled, Self-Balancing Service Platform
2019
Master's thesis Mechatronics MAS500 - University of Agder 2019 This thesis covers the design and development of a multi-mode, two-wheeled, self-balancing serviceplatform. The purpose of such a platform is to assist people with transportation tasks in crowdedspaces like airports by consuming as little space as possible and minimizing its overall footprint.This is solved by constructing a robot that can transition between bicycle and differential driveconfigurations and keep its balance in both configurations as well as in the transition processbetween them. A two-wheeled, self-balancing robot is an inherently unstable system that can bebased on the theory of an inverted pendulum. The unstabl…
Fixed speed wind turbine generator model validation and dynamic simulation using Matlab/Simulink
2007
In the last two decades an increasing amount of electricity has been generated from renewable sources in order to mitigate the environmental impact of the conventional power plants. In the next future wind turbines may affect the behaviour of electrical power system. This paper describes the model of a typical fixed speed wind turbine connected to the grid; the model is developed in the simulation tool Matlab/Simulink. It’s composed by the aerodynamic system, the shaft model (two-mass system), the induction generator (fifth order model) and the stall control system of the wind turbine rotor. The validation of the wind turbine model is made in steady-state operation, and the results are veri…
Kvadrotora sadarbība ar bezvadu sensoru tīklu
2016
Darbs ir par kiberfizikālajām sistēmām, kas ir strauji augoša datorikas apakšnozare. Pēdējos gados kvadrotoru un bezvadu sensoru tīklu tehnoloģijas ir vienas no nozīmīgākajām kiberfizikālajās sistēmās. To attīstības rezultātā ir radusies interese par šo tehnoloģiju apvienošanu vienā lietojumā. Darbā ir izpētīti dažādi kvadrotora un bezvadu sensoru tīkla sadarības piemēri, kā arī nepieciešamās tehnoloģijas to realizācijai. Darbs ir daļa no Artemis R5-COP projekta, un tas ir izstrādāts LUMII Reālā laika sistēmu laboratorijā. Darbā ir apskatītas LUMII pieejamā kvadrotora, bezvadu sensoru tīkla un MATLAB Simulink iespējas un dažādas lokalizācijas metodes. Darba ietvaros ir izstrādāts demonstrāc…
Parameters identification of the complex impedance model of the PEM fuel cell using Matlab/Simulink
2017
In this work, we present a new technical method for identifying the complex impedance model parameters of a Proton Exchange Membrane (pEM) Fuel Cell for on-board diagnosis in real time. The study of the PEM Fuel Cell modelling is important in order to understand the physical phenomena that occurring in this green renewable energy source. A diagnosis method is presented by analyzing the behavior of the complex impedance. For this, we present the identification method of the various complex impedance parameters; this identification is based on mathematical methods using the least squares method and the interpolation analysis method. The results are obtained using Matlab/Simulink tools and all…
Wind turbine modeling using the bond graph
2011
Author's version of a chapter in the book: Proceedings of the IEEE International Symposium on Computer-Aided Control System Design. Also available from the publisher at: http://dx.doi.org/10.1109/CACSD.2011.6044572 This paper addresses the problem of bond graph methodology as a graphical approach for modeling wind turbine systems. In this case, we consider the modeling of a wind turbine system with individual pitch control scheme and the interaction with tower motions. Two different bond graph models are presented, one complex and one simplified. Furthermore, the purpose of this paper is not to validate a specific wind turbine model, but rather show the difference between modeling with a cl…
