折叠系统组成
基于双DSP矢量控制的三相笼型异步电机驱动系统的变频器采用交直交电压型结构和SVPWM脉宽调制方式。系统由三相整流器、滤波电容、电压型逆变器、逆变器驱动电路、三相笼型异步电机和双DSP控制系统构成。
其中双DSP控制系统由VC33子系统，F240子系统和数据交换单元三部分构成。矢量控制以VC33芯片为核心，用来完成矢量控制核心算法，及两相电流检测。F240主要完成三相PWM波形生成，电机测速及过压保护功能。数据交换部分采用双端口RAM，可使两个DSP芯片迅速、方便地交换数据，增强了双DSP系统的并行处理能力。
折叠系统软件
系统软件由两部分组成，VC33子系统矢量控制软件和F240子系统的SVPWM控制软件。
矢量控制包含大量的数学运算，整个算法由多个模块构成，如坐标变换、磁通计算、速度调节及转矩电流调节模块等。本系统中电流内环的控制时间为50μs，速度外环为400μs，如图3所示为VC33子系统的控制软件流程图。
F240子系统控制软件主要完成SVPWM波形生成和电机测速程序，为达到良好的控制效果，本系统采用电压空间矢量，也就是利用六个非零电压矢量和两个零矢量的组合起来，使电压矢量尽量逼近圆周运动。转速测量用该芯片的脉冲捕获单元。如图4所示为F240的程序流程图。
