In this paper, using a personal computer (PC), the practical implementation of scalar and vector control methods on a three–phase rotor surface- type permanent magnet synchronous machine drive is discussed. Based on the machine dynamic equations and the above control strategies, two block diagrams are presented first for closed-loop speed controlling of the machine drive/system. Then, the desig...

A dialogue system that responds mechanically to given queries can be used for public relations prospective university students. However, as a user-specific problem, collecting information from first-time entrances and passive examinations is difficult, conventional may not collect sufficient information. Therefore, we developed recommendation-type supports gathering by evoking potential user re...
