| Abstract: | A method to automatically compensate the signal phase for photoelectid encoder base on phase shifter.This method carries the automatic compensation of signal phase by using FPGA to control digital poentiometers which replace the traditional method of using manual changing resistanc.The design principles,hardware circuit and algorithm are introduced simply.The tested results show that this method is effective to improve the measurement accuracy of optical encoder,and a good real-time compensatory. |
