In this article, to guarantee the good tracking performance of the precision motion system for
various tracking tasks, an online iterative learning compensation method is proposed for …

Many control methodologies have been applied to the motion control of linear motor drive
systems. Compensations of nonlinearities such as frictions and cogging forces have also …

In high-end testing and manufacturing equipment, a trend exists whereby the traditional
servo feed system with a ball screw and rotary motor will gradually be replaced by a direct …

This paper presents a novel disturbance compensation scheme to attenuate periodic
disturbances on repetitive motion using permanent magnet linear synchronous motors …

As direct-drive actuators, permanent-magnet linear synchronous motors (PMLSMs) are
widely used in high velocity and high precision applications. The detent force, however, can …

With the electrification and intellectualization of vehicle systems, electromagnetic active
suspension has been paid more and more attention. Linear motor is one of the effective …

This paper aims to solve a closed-loop identification problem for the space-periodic force
ripple in permanent-magnet linear synchronous motor (PMLSM) systems. Conventional …

In this paper, for periodic motion tasks, combining adaptive PID-type sliding mode control
(APIDSMC), model reference adaptive control (MRAC) and periodic adaptive learning …

The permanent magnet linear synchronous machine driven motion stage for the
semiconductor manufacturing equipment and machine tools has the basic requirement of …

In this article, an augmented generalized proportional–integral observer (GPIO) is presented
to estimate and then compensate for the disturbance/uncertainty both existing in the …
