Virtual and remote experimentation with the Ball and Hoop system
ABSTRACT Using Internet-based networking technologies traditional control laboratories in engineering education can be replaced with a remote or simulated experimental session. Thus, the way of studying becomes more flexible: the assistance to the laboratories is minimized. Accessing to the application students can make experiments and obtain results with a real plant from different localizations far from the university. This paper presents a complete virtual and remote control laboratory for experimentation of an oscillatory system: the ball and hoop. Using this application students can understand in a practical way important topics such as non-minimum phase behaviors, zeros transmission of the system, resonance, or to demonstrate control of oscillatory systems. The client-side of the virtual laboratory has been developed using the programming support provided by easy Java simulations (Ejs). The server-side has been developed using Labview and a data acquisition card.

ABSTRACT: New information technologies provide great opportunities for education. One such opportunity is the use of remote control laboratories for teaching students about control systems. This paper describes the creation of interactive remote laboratories (RLs). Two main software tools are used: Simulink and Easy Java Simulations (EJS). The first is a widely used tool in the control community, whereas the second is an authoring tool designed to build interactive applications in Java without special programming skills. The RLs created by this approach give students the opportunity to perform experiments with real equipment from any location, at any time, and at their own pace. The paper ends with an evaluation of this approach according to students’ criteria and academic results.Computers & Education 09/2011; 57(2):1686-1697.

ABSTRACT: This paper introduces interactive animations as a support resource for learning concepts of control systems. The animations are focused on three dynamic systems: a tank, a spring-damping-mass system and a roller-plane. The user can adjust the parameters and input variables, and observe the output variable behavior. The animations offer a learning environment, which allows students develop different activities to learn basic control concepts like Feedback, Modeling, time and frequency domain Analysis, Stability and Compensation without a detailed mathematical explanation. The animations propose an active learning environment through playing that engages students in the subject. The animations are developed by using Easy Java Simulations.Control & Automation (MED), 2013 21st Mediterranean Conference on; 01/2013

ABSTRACT: There is significant interest in hyperspectral image data in multiple disciplines. Laboratory-based hyperspectral imaging systems support research on samples ranging from plants and agricultural products to cell cultures, algae, coral, metals, and other media of interest. In most traditional laboratory settings, the user selects the data acquisition parameters and controls the instrument in the laboratory. In this paper interfacing a lab-based hyperspectral imaging system with the Internet through NI LabVIEW and related programs is described to allow real-time remote access and control of the system as well as viewing of the captured data. Through the designed interface, hyperspectral image cubes can be acquired and stored remotely, and viewed on-line by individuals who are not in the lab but are granted remote access to the system. The functional model for the remote control hyperspectral imaging system and the designed interface for real-time web-based data viewing and control are presented in this paper.01/2011; DOI:10.1109/AIPR.2011.6176372
