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 ...

Shape optimization of a PMLSM using Kriging and genetic algorithm

2010 5th IEEE Conference on Industrial Electronics and Applications, 2010
A low cogging force permanent magnet linear synchronous motor (PMLSM) having 9 pole 10 slot structure is presented in this paper. An optimization strategy employing Kriging model and genetic algorithm (GA) is proposed to reduce the detent force for high precision purpose application.

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 ...
