    A collaborative tool for synchronous distance education
    (2004-01-01) Agudelo, A.; Escobar, L.; Restrepo, J.; Quiroz, A.; Trefftz, H.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    In this paper we report results of the use of a telepresence application in a simulated distance education setting. The application combines video-conference with a networked virtual environment in which the instructor and the students can experiment with virtual object in a collaborative manner. The teaching for Understanding (TFU) framework is used as the pedagogical approach. Current preliminary results show that the combination of the telepresence application with TFU, can compensate for the lack of physical presence of the instructor in the classroom.

    Control and parameter estimation of a mini-helicopter robot using rapid prototyping tools
    (World Scientific and Engineering Academy and Society (WSEAS) Press, 2006-01-01) Vélez S., C.M.; Agudelo, A.; Universidad EAFIT. Escuela de Ciencias; Modelado Matemático
    This paper shows the control and parameter estimation of a mini-helicopter robot using a rapid prototyping environment based on Matlab/Simulink. The parameter estimation task is facilitated by the availability of a block-based visual simulation model and its integration in a general Matlab environment, with the feasibility of use of many other tools. The environment is integrated by modules which use common Matlab tools (ground control station, linearization, parameter estimation, heuristic identification) and own modules developed specifically for simulation, state estimation and multirate control. An example is presented in a software-in-the-loop context, showing all possibilities of the software environment including supervisory, estimation, linearization, and control tasks.

    Modeling, simulation and rapid prototyping of an unmanned mini-helicopter
    (2006-01-01) Vélez, C.M.; Agudelo, A.; Alvarez, J.; Vélez, C.M.; Agudelo, A.; Alvarez, J.; Universidad EAFIT. Departamento de Ciencias; Modelado Matemático
    This paper presents a rapid software prototyping environment (RSPE) for the design, simulation, and real-time implementation of a control system for an autonomous mini-helicopter. The software prototyping environment consists of diverse modules, including a mini-helicopter simulation model, a navigation filter, different controllers, a ground control station, and linearization and parameter identification tools. The environment is intended to reduce development time and costs, giving the designer more time to focus on mathematical and algorithmic methods. A hardware-in-the-loop (HIL) simulation example is presented to study the use and advantages of the prototyping environment in control design and simulation. Copyright © 2006 by EAFIT University.

    Multirate control of an unmanned aerial vehicle
    (World Scientific and Engineering Academy and Society (WSEAS) Press, 2005-01-01) Vélez S., C.M.; Agudelo, A.; Universidad EAFIT. Escuela de Ciencias; Modelado Matemático
    The application of multirate sampling to the control of an unmanned aerial vehicle (a mini-helicopter robot) using CACSD tools, developed specially for that goal, is presented. Multirate control is tested via simulation over the Matlab/Simulink mini-helicopter model, which is briefly described. A multirate modeling method is presented, which is the base of a CACSD tool for the modeling, simulation and real-time code generation of multirate control systems - the Multirate Control Toolbox (MCT).
