由于快速响应的、高精度的位置伺服系统正被广泛地应用于如存储器磁盘一类的计算机外部设备、自动机床、印刷用光学扫描机、晶片测试、集成电路掩膜加工机等很多场合,所以减小调整时间是一件非常重要的工作。生产效率的高低常因伺服系统调整时间的短长而异。为了提高上述机器的生产效率,把调整时间减小到一个最小的数值是颇有价值的。 Because of the rapid response, high-precision position servo systems are being widely used in many applications such as computer peripherals such as memory disks, automatic machines, optical scanners for printing, wafer testing, integrated circuit mask processing machines and the like It is a very important task to reduce the adjustment time. The level of productivity often due to servo system to adjust the length of time varies. In order to improve the production efficiency of the above machines, it is of great value to reduce the adjustment time to a minimum value.
