Mujun Xie received the Ph.D. degree in Optical engineering from Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun, China, in 1999. Her main research interests are industrial machinery fault diagnosis technology and intelligent machinery and robot control. Aiming at the machinery such as synchronous motor, air compressor which are widely used in modern industry, based on multi-sensor information fusion technology, the research on obstacle signal acquisition, processing, fault diagnosis and location is carried out to achieve fault prediction and judgment. Aiming at intelligent machinery and robot, multi-sensor information fusion vision measurement, system modeling and control strategy research are carried out to realize the robot position and attitude control.
