A Review on Disturbance Analysis and Suppression for Permanent Magnet Linear Synchronous Motor
Actuators, 2021 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 drive system.

International Journal of Mechanical System Dynamics, Volume 1, Issue 1, Page 35-51, September 2021., 2021 Abstract As one of the most advanced and precise equipment in the world, a photolithography scanner is able to fabricate nanometer‐scale devices on a chip. To realize such a small dimension, the optical system is the fundamental, but the mechanical system often becomes the bottleneck. In the photolithography, the exposure is a dynamic process.

Extended State Observer-Based IMC-PID Tracking Control of PMLSM Servo Systems
IEEE Access, 2021 Servo systems driven by a permanent magnet linear synchronous motor (PMLSM) are often affected by uncertain disturbances, such as magnetic resistance, friction, and external disturbances, which increase tracking errors and reduce motion accuracy ...

IET Power Electronics, Volume 14, Issue 4, Page 785-796, 18 March 2021., 2021 Abstract An adaptive backstepping complementary sliding mode control (ABCSMC) with dead‐zone parameter modification applicable to the permanent magnet linear synchronous motor is proposed in order to achieve high‐performance servo control fields. On the theoretical foundation of backstepping control and sliding mode control, a strong robust controller,

The design of a position-based repetitive control for speed ripple reduction in PMLSMs [PDF]
, 2017 Periodic speed errors can occur in permanent magnet linear synchronous machines for two reasons: 1) a periodic reference signal; 2) cogging force and friction. For reducing such periodic errors, iterative learning control or repetitive control approaches,

Teeth Arrangement and Pole–Slot Combination Design for PMLSM Detent Force Reduction
Energies, 2021 This paper introduces and investigates a new design method that employs both teeth arrangement and pole–slot combination to reduce the detent force of permanent magnet linear synchronous motors (PMLSMs) for precision position control.
