摘要Abstract: In the paper, the control system of a computerized flat knitting machine is designed and implemented. A permanent magnet synchronous motor is used to operate the machine. We design the motor drive that discrete power MOSFETs are adapted in the inverter to reduce the cost. In order to get zero steady-state error, the PI control is considered in the velocity control loop. Microcontroller, 8052, programs the drives of seven step motors to manipulate the controls of cam, left stitch, and right stitch of front-end and back-end, and racking. The color and style of the accessories of clothing is programmed by using the keyboard, PC, or the external memory card. There are three communication protocols, RS232, RS422, and RS485, used in the system to transfer the instructions and data.
