Design Requirement And stitiches types - VS SewingMachine

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.

Within this context, it is necessary to schedule the moments of replacing the sewing needles of the embroidery machines based on the anticipation of their failure moments.
In the past years, through the development of different types of sensors, the scheduling of the replacement of components has been moved from a statistical approach to a conditionbased maintenance . Modern diagnostic techniques use sensors that determine the state of the equipment by comparing the signals received from the sensors at a given moment with signals corresponding to their good functioning
