Permanent Magnet Synchronous Motor Feedback Linearization Vector Control
2013In order to solve the control problem of a class multiple-input multiple-output nonlinear system, the feedback linearization method is introduced. By calculating the output variables of Lie derivative, the appropriate coordinate transform and nonlinear state feedback are obtained, then through the coordinate transformation and state feedback, the input-

Adaptive friction compensation for permanent magnet linear synchronous motor
2009 Chinese Control and Decision Conference, 2009The paper discussed an adaptive friction compensation scheme based on Coulomb friction and a parameter identifier. The model reference adaptive system based on Coulomb friction was designed to compensate the friction on-line. The designed model reference adaptive parameter identifier was combined with the adaptive friction compensation system and the ...

Sensorless vector control of linear permanent magnet synchronous motor
2013 IEEE ECCE Asia Downunder, 2013A practical vector control algorithm for speed control of linear permanent magnet motor without a position sensor is presented. The vector control algorithm is based on decoupled control of d and q-axes currents. The errors in the d and q-axes currents are used as inputs to the two PI controllers to generate the orthogonal d and q-axes components of ...

Thrust Ripples Suppression of Permanent Magnet Linear Synchronous Motor
IEEE Transactions on Magnetics, 2007The thrust ripples in permanent magnet linear synchronous motor (PMLSM) are mainly generated by the distortion of the stator flux linkage distribution, reluctance force due to the relative position between the mover and stator, cogging force caused by the interaction between the permanent magnet (PM) and the iron core, and the end effects.

Fuzzy Impulsive Control of Permanent Magnet Linear Synchronous Motors
Applied Mechanics and Materials, 2014The permanent magnet linear synchronous motors (PMLSMs) may have chaotic behaviors. So the Takagi-Sugeno (T-S) fuzzy impulsive control model for PMLSMs with parameters uncertainties is established. The stability for PMLSMs is derived by Lyapunov method and matrix analysis. An illustrated example is also given to show the effectiveness of our results.

Interior Permanent Magnet Synchronous Motor Linear Field-Weakening Control
IEEE Transactions on Energy Conversion, 2016At nonlinear field-weakening control of interior permanent magnet synchronous motor (IPMSM), the working point is difficult to calculate and the saturation of current regulators may lead to losing control. Linear field-weakening control (LFC) of IPMSM is proposed to control both torque and current in wide speed range applications and LFC can prevent ...
