Detent force analysis and structure improvement of PMLSM

2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011
Detent 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.

Topology Optimization with Hybrid Algorithm in End teeth of PMLSM

2021 13th International Symposium on Linear Drives for Industry Applications (LDIA), 2021
In order to reduce the end effect of permanent magnet linear synchronous motor (PMLSM) on thrust ripple, a hybrid algorithm based on topology optimization is proposed to optimize the end teeth of PMLSM. Compared with the traditional geometry parameter optimization scheme, the hybrid optimization algorithm based on Tabu search and ON/OFF method is more ...

Reduction techniques of the end component of PMLSM

2010 Second Pacific-Asia Conference on Circuits, Communications and System, 2010
the 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.

A simulation model of PMLSM based on physical platform

Proceedings of the 33rd Chinese Control Conference, 2014
The model of permanent magnet linear synchronous motor (PMLSM) is complex, and the ready-made PMLSM block can not be found in Matlab during the process of simulation. A lot of simplified models are not compared with the physical object and can not reflect the actual well, so that a lot of advanced algorithms will not be used in the actual effectively ...

An ESO-Based Repetitive Controller Design for PMLSM

2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019
For rejecting aperiodic disturbances at the moment of loading, following the periodic velocity reference signals better, and realizing the precise velocity tracking control in Permanent Magnet Synchronous Linear Motors (PMLSMs), an extended state observer based repetitive control strategy (ESO-RC) is proposed in this paper.

Application and Prospect of the PMLSM Driver on Grinding Machine

2006 6th World Congress on Intelligent Control and Automation, 2006
Permanent magnet linear synchronous motors (PMLSM) is much superior to the traditional ones driven by rotating motor with the transition elements, but its control system is much more complex. To the model uncertainty and disturbance in grinding, a robust velocity controller was designed according to the frequency characteristic of the system and the ...

A New Sensorless Design for PMLSM Servo Control System

2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009), 2009
In this paper a new method to inspect the speed and position of linear motor is presented. We find the mathematical model of PMLSM in the rotationary dq coordinate contains the nonlinear term and it satisfies Lipschitz conditions. So we introduce an observer design method for Lipschitz nonlinear systems in the presence of bounded disturbances and give ...
