Fuzzy predictive control strategy of permanent magnet linear synchronous motor

open access: yesJournal of Hebei University of Science and Technology, 2020
In order to solve the problem that the actual current cannot closely follow the given current or the predicted output voltage fluctuates too much due to the unreasonable selection of the weight coefficient when the model predictive control seeks the ...

Impact of the motor magnetic model on direct flux vector control of interior PM motors [PDF]

open access: yes, 2011
The stator-field-oriented, direct-flux vector control has been proven to be effective in terms of linear torque control and model independent performance at limited voltage and current (i.e. in flux weakening) for AC drives of various types.

Feedback Linearization Based Robust Control for Linear Permanent Magnet Synchronous Motors [PDF]

open access: yesEnergies, 2020
In this study, we designed a feedback linearization control strategy for linear permanent magnet synchronous motors (LPMSMs) as well as a robust control mechanism. First, the highly nonlinear system was transformed into an exact linear system by the feedback linearization technique. Then, we designed a robust controller to mitigate the impact of system
