| Abstract: | The position detection of electric machine is the key technologys of servo control. On the basis of the analysis of the detection of the grating encoder signals, it finds a solution to the receiving and disposal of the signals, and confirms the sampling period, At the same time, the scheme used to control the electric machine of Two-dimensional Moving Mechanism is determined based on PID, through which the control of the electric machine with high response and high precision can be realized. |
