As people pursue the continuous improvement of material life,Clothing for style and quality requirements are getting higher and higher. To achieve such conditions,we must improve the stability and driving accuracy of the sewing machine. At present,the Spindle control of sewing machine relies mostly on control stepper in china,which is always out of step that lead to Large errors. Although Special sewing machines have high precision abroad,their price is expensive as well. According to the current background,This paper presents a brushless DC motor servo control system based on DSP,seting up Mathematical model,and design a fuzzy PID controller,which controls accurately Sewing machine needles for speed and position.
