Analysis of Predictive Current Control Method for Permanent Magnet Synchronous Motor in Machine Tools
This paper expounds the analysis model predictive control problem of extended voltage vector sets,and analyzes the control method of predicting current for permanent magnet synchronous motors used in machine tools through virtual appropriate construction and model predictive control.Based on simulation and platform experiments,it has been verified that the use of predictive direct current control can achieve ideal steady-state current control effects,manifested by a significant decrease in the total harmonic content of the current and a significant reduction in the amplitude of low order harmonics of the current.
