Research on Linear Motor Driving System Based on Wavelet Transform

Abstract

End-effect is a main reason of influence on the characteristic of linear motor driving system, its direct impact is nonstable and undulate edges magnetic field. The wavelet transform is applied to analyze the linear motor driving system performance in this paper. The improving thrust response system has been presented based on choice wavelet function and wavelet transform. Simulation results indicate that the proposed control strategy can abate the thrust ripple problem caused by end effect in linear motor control system, and make the system have good performances
