| Abstract: | 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. |
