With the development of the modern manufacturing industry, especially that of high-speed
and high-precision machining, higher performances of computer numerical control (CNC) …

Establishing accurate dynamic models in a form that is suitable for integration with model-
based control methods, is of great significance for further improving the dynamic motion …

A servo drive system with a permanent magnet synchronous motor (PMSM), ball-screw, gear
and timing-belt is widely used in industrial applications such as numerical control (NC) …

In order to provide guidance and reference for develo** a ball screw drive system of the
high-speed machine tool, this article investigates three basic issues with consideration of …

This paper presents an optimal non-collocated control strategy for flexible ball-screw feed
drives. Within the non-collocated controller framework, all the feedback measurements are …

Permanent-magnet synchronous linear motors (PMSLMs) are more and more frequently
used as all-electric direct-drive actuators in those applications where a force needs to be …

In this paper, a two-loop control structure for the constrained tip regulation of a linear-motor-
driven flexible beam is developed to achieve high performance. Specifically, in the inner …

This paper proposes a parallel structure of a feedback controller for the ball-screw drive
systems which have significant dynamic variations during operations. The controller consists …

This paper proposes a method that estimates the parameters of a velocity-controlled servo.
A proportional-integral controller, which uses only position measurements, closes the loop …
