基于工业缝纫机控制的核心是转矩,采用DSP芯片TMS320LF2406A实现永磁同步电机空间矢量脉宽调制(SVPWM)控制器的控制原理,给出了一种基于精确的光电编码信号测速的无电流环直接电压控制策略来设计工业缝纫机控制器的硬件组成结构及软件设计流程。
The core of industrial sewing machine control is the torque. The control principle of space vector pulse width modulation (SVPWM) controller for the permanent magnet synchronous motor (PMMSM) based on DSP chip TMS320LF2406A is realized. A current-free loop based on accurate photoelectric coding signal is given Voltage control strategy to design the industrial sewing machine controller hardware structure and software design flow.
