Abstract :
The conventional algorithms applied in industrial sewing machine (ISM) have some disadvantages such as less precision, lower speed response and more complicated due to the special requirement of the ISM. Taking the mechanical characteristics of ISM into consideration, a changing-dead-zone multi-segment-PID with digital filter algorithm is presented in this paper, which is applied in the speed control of the brushless DC motor (BLDCM) servo system. The improvement process of the arithmetic is specified in the paper. The mathematical model of the speed control of servo system is built by MATLAB/Simulink, and the online simulation is implemented on the software-hardware platform provided by hardware-in-the-loop simulation (HILS) tool dSPACE. The simulation result is showed that the improved algorithm is more effective in the dynamic performance of the system compared with the increment-PI, and it also works well in the application of the practical product of ISM
