基于DSP28335的永磁同步电机调速系统设计摘要（中英文）     本控制系统的设计是为了实现基于TMS320F28335的永磁同步电动机的调速系统，并把它引用到全电动注塑机当中。本系统使用SVPWM的控制方法，通过采样电机电流和旋转变压器的位置信息，实现速度、电流双闭环控制。通过TMS320F28335的硬件浮点处理核心 ...

If register should be written or read.This value is passed to the calback functions which support either reading or writing register values. Writing means that the application registers should be updated and reading means that the modbus protocol stack needs to know the current register values.See a ...
