摘　　要：为了满足某些运动系统对转速测量高精度的要求,本文提出了虚拟编码器的设计方法。与测速发电机、光电码盘等测速方法进行的实际对比说明了虚拟编码器应用于转速测量的优越性。通过在智能车与钻石研磨机上使用虚拟编码器进行转速测量的实践,验证了虚拟编码器应用于高精度转速测量的有效性。In order to satisfy the requirement of high accuracy rotation speed measurement in moving systems, the concept of virtual coder has been put forward. Through comparing virtual coder with speed generator and common coder, the strongpoint of virtual coder is shown. Rotation speed measurements in diamond grinding machine and intelligent car using virtual coder are used as examples, and the measurement results prove that the virtual coder can be used for high accuracy rotation speed measurement effectively.
