2 特点 矢量控制中的典型计算由矢量引擎处理.因此,可以降低CPU 工作于矢量控制的软件负荷.此削减可改善用户的系统性能,因为 CPU资源可分配给PFC,传感器处理,或者通信系统. 此外,如果控制两个电机,矢量引擎显著削减CPU处理时间. 当两个电机由全软件进行矢量控制时,CPU的时钟速度一定会因此 而增加,同时会增加工作电流;

因此用户需要考虑电源,散热,以及EMC.如果矢量引擎和CPU一起使用,并列执行两通道的计算, 在没有高速CPU时钟的情况下就可以改善两个电机的计算处理效 率. 随系统配置和控制方法而变化的位置估算和速度控制留给软件处理,矢量引擎处理包括三相电机电流到二相的转换,或者旋转坐标 的转换/逆转换的典型计算.矢量引擎的任务配置为一个调度程序.任务的组合多达 16种.这些各种类型的调度程序给电机控制提供了 更高的灵活度,并且矢量引擎可以支持多种类型的电机工作. >
