摘要
介绍了一种由DSP+FPGA构成的全数字化异步电机控制系统,着重介绍了TMS320LF2407A与EP1K30TC144之间的数据传输方法,给出了DSP和FPGA的硬件连接示意图以及相应程序.最后采用正弦脉宽调制方法(SPWM)验证系统正确性.实践表明本系统结构简单、可靠,可作为直接转矩控制、空间矢量控制等现代高性能控制算法的实验硬件平台.
This article introduces a digital control system of asychronous motors, consisting of DSP and FPGA, with emphasis on a data transmission method between TMS320LF2407 and the EP1K30TC144, and gives a hardware connection scheme of DSP and the FPGA as well as the corresponding procedure. In the later part, there is an experiment employing the sine pulse-duration modulation method （SPWM） to confirm the system accuracy. The practice confirms that this system is simple and reliable, and can be used as the experimental hardware platform for the modern high performance control algorithm, such as the direct torque control algorithm, space vector control algorithm and so on.
