Using a Remote Lab for Real Physical Measurements on an Electric Motor

2012

Int. J. Onl. Eng.

Abstract-Remote laboratories are normally developed for giving students and others remote access to physical laboratory facilities. In contradiction to this, the main objective of the setup presented in this paper is to create a controlled environment where unwanted side activities like hardware setup, driver problems, troubleshooting faulty components, and struggles with special software for configuring DSP systems, are removed as much as possible, in order for the students to have their full focus on the tasks that is considered relevant for the module: modeling of non-linear systems, synthetisation of controllers, and stability and performance analysis. A secondary objective is to significantly reduce the setup and maintenance cost associated with complex laboratory setups involving DSPs and expensive hardware.

Experiment Setup for Focused Learning of Advanced Servo Control of DC-motors

2012

Int. J. Onl. Eng.

“…In some cases the remote laboratory is used as a substitute for the physical laboratory, while in other cases this is used as an addition to the traditional exercises as reported in [5] and [6], where the laboratory is integrated in the exercise program together with physical, hands-on laboratory, normal problem solving, as well as simulations. This is done in order to improve the quality of the exercise program.…”

Virtual fences as protection against damage on physical equipment used in remote laboratories

2012 9th International Conference on Remote Engineering and Virtual Instrumentation (REV)

The topic of this paper is to present a strategy for prevention of damage on laboratory equipment used in a remote laboratory. The laboratory is used for verification of control algorithms for quad rotor helicopters through practical experiments. The damage control strategy should not limit or impede the natural movement of the equipment as long as the behaviour is kept within predefined limits. The nature of the system to be controlled, exclude the use of physical constraints that are normally used for damage control, as these in some way or another will impede or limit the movement of the helicopter.

“…This means that the quality of the tutoring will in some way be affected by the introduction of the remote laboratory. In some cases the remote laboratory is used as a substitute for the physical laboratory, while in other cases this is used as an addition to the traditional exercises as reported in [5] and [6], where the laboratory is integrated in the exercise program together with physical, hands-on laboratory, normal problem solving, as well as simulations. This is done in order to improve the quality of the exercise program as a whole, and to remove some of the disadvantages of running the laboratory program purely on remote laboratory platforms.…”

Dual Control System for Virtual Protection of a Remote UAV Experiment

2012

Int. J. Onl. Eng.

Abstract-The topic of this paper is the utilisation of a strategy with a dual control system for the prevention of damage on laboratory equipment used in a remote laboratory. One control system is implemented before the laboratory is deployed and is responsible for damage control and can override the second control system that is programmed by the user of the remote laboratory and is fully configurable. The laboratory is used for verification of control algorithms for quad rotor helicopters through practical experiments. The damage control strategy should not limit or impede the natural movement of the equipment as long as the behaviour is kept within predefined limits. The nature of the system to be controlled, exclude the use of physical constraints that are normally used for damage control, as these in some way or another will impede or limit the movement of the helicopter.
