Development of embroidery machine vector control speed regulation system based on DSP

Abstract

Based on the rotor field oriented control principle and space vector PWM technology, a vector control speed regulation algorithm applied to embroidery machines is developed based on DSP. Combined with the theoretical analysis, a kind of Anti-Windup PI controller is adopted based on output feedback calculations, and a discrete simulation model of the vector control speed regulation system is built on Matlab/Simulink platform. After the completion of the system hardware design, the entire control system software design and programming are completed based on the TMS320F2801 fixed-point DSP. Results of simulation and experiments show that the designed system meets the needs of a practical application in spindle actuator of the embroidery machine.
