Considering from core losses in modeling the reluctance synchronous motor7th International Workshop on Advanced Motion Control. Proceedings (Cat. No.02TH8623) - - Trang 251-256
C.A.M.D. Ferraz, C.R. de Souza
Synchronous reluctance motor figures of merit have been improved thanks to the
technological evolution of the materials its rotor is made of. Other factors,
like new control strategies, the developments of power semiconductors and
digital electronics have also played an important role in making possible this
improvement. Owing to this development, it is now possible to consider this
category of mo... hiện toàn bộ

Repetitive controller design for track-following servo system of an optical disk drive7th International Workshop on Advanced Motion Control. Proceedings (Cat. No.02TH8623) - - Trang 176-181
Tae-Yong Doh, Jung Rae Ryoo, Myung Jin Chung
In the track-following servo system of an optical disk drive, external
disturbances with significant periodic components cause tracking errors of a
periodic nature. To effectively reject such disturbances, repetitive control has
been employed. However, plant uncertainty makes it difficult to design a
repetitive controller which both ensures system stability and improves tracking
accuracy. In this ... hiện toàn bộ

Limitations in control of elastic servos with co-located sensors7th International Workshop on Advanced Motion Control. Proceedings (Cat. No.02TH8623) - - Trang 92-97
G. Ferretti, G. Magnani, P. Rocco
Performance limitations of elastic servomechanisms where only the motor position
is measured emerge considering also the load position behavior. Limitations
inherent to PID control, the most common solution in commercial products are
dealt with first. The authors explicitly relate a bound of the H/sub /spl
infin// norm of the motor position setpoint to load position transfer function

This paper presents a rehabilitation support system for the exercise of upper
limb motor function. The system supports occupational therapy for recovering
physical function and is used for reaching exercise of the upper limbs,
especially the shoulder and elbow joints. This system is effective for people
with advanced problems. It allows patients with motor dysfunction of the upper
limb to keep mot... hiện toàn bộ

A new approach for flux and speed estimation in induction motor7th International Workshop on Advanced Motion Control. Proceedings (Cat. No.02TH8623) - - Trang 148-152
M. Dal, A. Sabanovic
A structure of the induction machine flux and speed observer is proposed. The
observer is designed in the stationary frame of references to avoid errors
affiliated with the coordinate transformations. In order to ensure the
convergence in any operational conditions a nonlinear additional term is added
to the observer structure. Full stability analysis based on the Lyapunov
stability method is deri... hiện toàn bộ

High efficiency SVM technique for VSI7th International Workshop on Advanced Motion Control. Proceedings (Cat. No.02TH8623) - - Trang 269-274
C. Attaianese, D. Capraro, G. Tomasso
A space vector modulation technique for voltage source inverter which takes into
account the power modules switching losses is presented in the paper. It is
based on three digital separate circuits, which generate the modulation
switching pattern by using a clock unit with three separate programmable
frequency divisors. In particular, for each leg of the inverter, the switching
frequency can be se... hiện toàn bộ

High speed robust visual servoing based on intersample estimation and multirate control7th International Workshop on Advanced Motion Control. Proceedings (Cat. No.02TH8623) - - Trang 104-109
H. Fujimoto, Y. Hori
This paper presents a visual servoing system based on intersample estimation and
disturbance rejection. First, a novel design method of a multirate sampling
controller is proposed which enables to reject disturbance completely at M
intersample points in the steady state. Second, the intersample observer is
developed in order to reduce the phase delay caused by zero-order hold and to
increase the s... hiện toàn bộ

An on-line reference-trajectory generator for smooth motion of impulse-controlled industrial manipulators7th International Workshop on Advanced Motion Control. Proceedings (Cat. No.02TH8623) - - Trang 365-370
S. Liu
Industrial manipulators driven by impulse-controlled servo motors commonly
follow prescribed reference-trajectories which enable smooth movements (no
discontinuity in acceleration profile). On-line generation of such smooth
trajectories as a consequence of new target-settings during the motion, however,
still suffers from the high computational effort for calculating an optimum
solution, as far as... hiện toàn bộ

Run time position estimation with basic sensors in real time SCADA applications7th International Workshop on Advanced Motion Control. Proceedings (Cat. No.02TH8623) - - Trang 583-587
E. Ozdemir, M. Karacor
In this study, a novel real time SCADA (supervisory control and data
acquisition) algorithm for position estimation of an object moving on a plane
(e.g. an object on a moving conveyor band) is proposed by using basic sensors
(e.g. limit switch, proximity sensor etc.). This algorithm is explained on a
sample band system application.
