Design of PMLSM CMAC-PID controller
2020 International Conference on Artificial Intelligence and Electromechanical Automation (AIEA), 2020PMLSM has the advantages of high reliability, high thrust and fast response, and is widely used in semiconductor and automation equipment. Compared with the traditional rotary motor, it can directly drive the load, thus greatly improving the efficiency.

Research on iterative learning control of PMLSM
2010 International Conference on Mechanic Automation and Control Engineering, 2010Some inherent nonlinear interference factors of iron-core PMLSM are main factors that influence its trajectory tracking performance. In order to improve the tracking precise of linear motor, on the basis of PID controller, two kinds of iterative learning controller based on pulse transfer matrix are proposed.

Research on ropeless elevator driven by PMLSM
2016 Eleventh International Conference on Ecological Vehicles and Renewable Energies (EVER), 2016The permanent magnet linear synchronous machine (PMLSM) with long primary is a suitable candidate for ropeless elevator due to high force density and low thrust ripple. For the PMLSM with multi-segment long primary, it is impractical to excite all primary segments.

Reduction techniques of the end component of PMLSM
2010 Second Pacific-Asia Conference on Circuits, Communications and System, 2010the cause of thrust ripple of PMLSM is the detent force producing shake and noise, at the lower speed region, control performances become increasingly deteriorated. Distributing characteristic of the end component at holly journey in PMLSM was analyzed using finite element method.

Detent force analysis and structure improvement of PMLSM
2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011Detent force is the main component of thrust ripple which is one of the unique characteristics of permanent magnetic linear synchronous motor (PMLSM). This paper briefly analyzes the causes and features of the detent force, and presents an improved structure of PMLSM on the basis of position shift and phase shift superposition method of multiple motors.
