Adaptive Speed Control of Three-Phase Induction Servo-drives Based on Feedback Linearization Theory

In this paper, based on feedback linearization control method and using a special PI (propotational integrator) regulator (IP) in combination with a feed-forward controller, a three-phase induction servo-drive is speed controlled. First, an observer is employed to estimate the rotor d and q axis flux components. Then, two input-output state variables are introduced to control the dynamics of to...

Creating Metadata for Children's Resources: Issues, Research, and Current Developments

A key challenge to retrieval in any type of system is how to represent the resources appropriately so that the user(s) can fi nd what they are looking for. In systems being used by children, as well as those designed specifi cally for children, there exist two fundamental representation problems: (1) the metadata or representation scheme of the system may not be designed with this specifi c use...
