【Abstract】 Along with the endless development of modern industry and intelligent, permanent magnet AC servo system has become one of the CNC servo system research focus. With the development of the industrial sewing machine control system, servo system needs to develop better performance and stability.Based on the above technical requirements, this paper researched on the permanent magnet synchronous motor and heavy duty sewing machine and deduction heavy duty sewing machine servo control system based on IRMCK201. From needs and the functions for the heavy duty sewing machine, this system determined the servo drive control scheme based on DSP and IRMCK201, selected ON Semiconductor’s switching power supply chip and IR’s intelligent modules as the core of the device drive circuit. Proceeding from the above devices, this system detailed designed the drive current, the control circuitry, external fittings circuit, protection circuit and other hardware for the heavy duty sewing machine servo control system. Through a lot of debugging, this system analyzed the hardware reliability and stability, built hardware debugging platform for heavy duty sewing machine which automatic controls the sewing machine.On the hardware debugging platform, permanent magnet synchronous motor field-oriented vector control algorithm achieved through controlling the IRMCK201 with the DSP. Permanent magnet synchronous motor running used current loop and speed loop PI control and dead-zone integral discrete PID position control loop algorithm.After hardware and software testing, this system reached the needs of heavy duty sewing machine, proved the feasibility of higher cost and stability, had a good market prospects.更多还原
