New methodologies in teaching e-structural mechanics using www
No full textA recently initiated phase of experimentation and research in the online Distance Learning (DL) is here described. The project has been developed by the Department of Construction and Transportation Engineering of the Faculty of Engineering at the University of Padua along with the well-established e-learning experience of the SSIS Veneto (Institute for the Formation of Secondary School's Teachers) of Cà Foscari—University of Venice, in collaboration with the webmaster management of TCN-EnginSoft of Padua. The work deals with teaching methodologies supported by the net, computer communication and information technologies, finalized to give both widespread access to useful resources and to create a more flexible exchange due to net communication. The experimentation of using web-based technologies to support traditional teaching for working students is described; in fact, Internet-based innovations offer opportunities for a curriculum improvement to those categories of students who could be considered at a disadvantage, like worker students or students with ear or motion deafness
On-Line Tracking of the MTPA Trajectory in IPM Motors Via Active Power Measurement
No full textThe real-time tracking of the Maximum-Torque-Per-Ampere (MTPA) trajectory in Interior-Permanent-Magnet (IPM) motors is addressed in this paper. The considered approach is based on the injection of proper current test signals and aims at minimizing torque oscillations at the injected frequency, this last condition assuring MTPA operations. Differently from previous approaches motor active power is monitored to detect the out-of-MTPA condition (i.e. torque oscillations), instead of measured motor speed, thus avoiding the use of high-resolution speed transducers, as required by previous approaches. Analytical development are provided, as well as simulation and experimental results, proving the effectiveness of the proposal
Automatic Tracking of MTPA Trajectory in IPM Motor Drives Based on AC Current Injection
No full textThe paper deals with a novel approach for the real-time tracking of the maximum-torque-per-ampere (MTPA) trajectory of an IPM motor drive. The proposed approach is based on the injection of proper tests signals and allows the MTPA trajectory to be learned and updated in the drive during steady-state conditions. The analytical development of the estimation algorithm, supported by a complete validation by simulation, is given in the paper. Finally experimental results are presented based on a prototype IPM drive system
