摘要
Abstract
Optical-incremental encoder,which is also called photoelectric anger-position sensor,is the core of device in measurement of motor speed and rotor position in driver system.The article researches on the incremental photoelectric encoder and analyzes its four fold frequency multiplication principle.It gives a method based on FPGA to multiply the signal of the incremental photoelectric encoder,differentiates its phase and counts its number.It has improved resolving power of coder and realized signal detection and position servo control of high accurate and high stable.The result indicates that the system can effectively eliminate noise and dither.The capability of restraining disturbing is improved.It is heritable and upgradable.关键词
