摘　　要：本文介绍了通过在PIC单片机中嵌入PID算法,实现了对电机转速的精确控制,从而达成了Indoor GPS测量系统扫描平台匀速扫描的目的,并利用Matlab通过RS422实现串口通讯,不仅方便了PID参数整定的图形化调节,而且可以将实时采集到的转速值用于后续测量环节。整个设计方便实用,可靠性强,并且能保证一定的精度,满足Indoor GPS系统的测量要求。A method to realize the controlling of motor speed by PIC18F248 embedded with PID algorithm is described. This leads to a scanner with a certain speed which is necessary for the Indoor GPS Metrology. And the measured data is transmitted to Matlab by serial communication, which not only helps the PID tuning, but also can be helpful to the following measuring steps, The design is convenience and reliable. It provides a certain precision that satisfy the Indoor GPS Metrology.
