随着数字电路以及微处理器技术的发展，直流传动的控制技术正在逐步由模拟控制方式向数字（智能）控制方式过渡。当前国内所广泛使用的智能化数字控制设备主要依靠国外进口，其中，德国AEG公司于90年代初推向中国市场的MINISEMI－D、MAXSEMI-D、ISA-D3个系列的产品都扮演着重要
With the development of digital circuits and microprocessor technology, the control technology of DC drive is gradually being transferred from analog control mode to digital (smart) control mode. At present, the intelligent digital control equipment widely used in China mainly relies on foreign imports. Among them, MINISEMI-D, MAXSEMI-D and ISA-D3 series products which German AEG Company introduced to the Chinese market in the early 1990s all play an important role
